Coauthors:The article that follows was written in 1994, and first appeared in The American Scholar (vol. 63 p. 527). In the three years since then much has happened, but little has changed. There have been reports of increasingly reliable production of excess heat, and of the detection of 4He residue, and much more. Nevertheless, the most remarkable fact remains that cold fusion has neither been accepted by mainstream science, nor has it withered away. The general situation that the article describes still seems to be in place today.

We can not help remembering that in the Soviet Union investigations of a number of abnormal phenomena which later were related to the problem of Cold Nuclear Fusion were carried out long before Fleischmann and Pons announced their experiments at the American University of Utah.
At present these kind of research works are widely carried on in Russia despite the absence of any state support and while part of the official scientific community remains skeptical.
In total there are more than 30 groups of scientists engaged in research in this field in Russia . . .

Abstract
The energy balance between heat excess and 4He in the gas phase has been found to be reasonably satisfied even if the low levels of 4He do not give the necessary confidence to state definitely that we are dealing with the fusion of deuterons to give 4He. In the melted cathode, the data of which are reported, no 4He was found at the achieved sensitivity. X-ray film, positioned at 50 mm from the cell, roughly gave the image of the cathode through spots. Extended considerations have been made to explain this evidence on the basis of the bundle nature of the cathode. From these considerations, the energy of the radiation and the total energy associated to it have been estimated as 89 keV and 12 kJ, respectively. This value is :0.5% of the energy measured by calorimetry in the same interval of time. The highest values of energy and excess power are 8.3 MJ and 10 W, respectively.
Grabowski, K.S., et al. Evaluation of the Claim of Transmutation of Cesium to Praseodymium with the Mitsubishi Heavy Industries (MHI) Structure -- Part 1 (PowerPoint slides). in 15th International Conference on Condensed Matter Nuclear Science. 2009. Rome, Italy: ENEA.
Coauthors: Kidwell, D., Cetina, C., Carosella, C.The MHI claim to transmute elements upon permeation of deuterium though a specific multilayer structure was carefully evaluated. Initially, an attempt was made to replicate the work at NRL in collaboration with MHI. When replication proved difficult, another set of experiments were conducted at MHI in three sets consisting of two control blanks and one positive foil (that should have transmuted Cesium to Praseodymium) per set. Foil samples were split for analysis at both NRL and MHI. Extensive analytical work was performed to characterize the foils and the blanks. When extracted at MHI, low nanogram amounts of Pr were found by ICP-MS on 3 of 3 foils that should have had Pr whereas the 6 controls were blank. Split solutions of these extracts were also tested independently at NRL and the presence of Pr was confirmed. The Pr found did not have the characteristic rare earth contamination expected if the Pr was from the environment and thus looked like it was produced in the experiment. Unfortunately, we could not find Pr at NRL (even at trace levels) on our split foil samples no matter what extraction method was employed. After considering and evaluating several unlikely scenarios for these disparate results, we visited MHI and participated in the extraction process on new foils. These extracts were blank when tested at both laboratories. Environmental samples were obtained at various locations where samples were handled. Pr was found in large amounts at one location used in sample preparation and this Pr had the signature of pure material rather than an inadvertent contaminate. No record of how it got there could be established. Other rare and characteristic impurities also were found in the extracts from MHI that were present in the laboratory environment. Thus, we concluded that the transmutation of Cs to Pr when deuterium permeated MHI’s multilayer structure could not be firmly established, as contamination during the foil production or during the foil analysis could not be ruled-out. The design of the replication experiments, the lessons learned, and the results will be discussed.

Coauthors:Open Source Science (OSSc) is a collaborative, voluntary (uncompensated) and highly distributed method of research that emphasizes the power of new digital technologies, particularly the Internet. The OSSc paradigm grew out of the open source software movement of the last 20 years, which has resulted in wide availability of free software (such as the Linux operating system) as an alternative to proprietary software products. In many respects, OSSc represents a return to the concept that scientific research results are a public good rather than a proprietary product -- an attitude clearly articulated in the 1940s by Robert Merton, the “father” of the sociology of science.

Coauthors: Wadsworth, M. E.Deuterium loading of palladium cathodes in Pons-Fleischmann type electrolytic cells has been observed to result in generation of excess heat on several occasions. Metallurgical examination of some of the electrodes showed extensive damage associated with deuterium loading. Surfaces have been found to be covered with large number of impurities. Initiation and sustaining these heat bursts, monitoring of nuclear products and materials aspects of these electrolytic cells have been the focus of our current efforts. As D/Pd loading appear to be critical, the measurement of deuterium loading using dilatometry as a function of current density, surface and heat treatment of the cathode and poisoning are currently being investigated.

ABSTRACT
Results will be presented for the surface analyses of cathodes before and after electrolysis using X-ray Photoelectron Spectroscopy (XPS). Composition as a function of depth was obtained by employing argon ion sputtering to gradually erode away the surface. Although most of the emphasis will be on Naval Research Laboratory (NRL) Pd (i.e., Johnson Matthey high purity sponge processed into rod and plate at NRL), data will also be presented from other Pd sources and from reported excess heat-producing cathodes provided by SRI International and NAWC, Naval Air Warfare Center at China Lake, CA. XPS results will be compared with bulk sample cathode and anode analyses obtained by Glow Discharge Mass Spectroscopy (GDMS) and with electrolyte solution analyses obtained by Inductively Coupled Plasma (ICP) Spectroscopy.

Abstract
We review highlights of the international cold fusion conference that was held recently in Nagoya, Japan. Excess heat results in heavy water electrolysis experiments constitute the observations with the most important potential applications. Experiments in gas phase systems exhibit fast particle and gamma emission that make progress toward elucidating mechanisms. The evidence in support of a light water heat effect has improved.

ABSTRACT
Nuclear reactions in a lattice are described using an extension of the resonating group method to include the lattice explicitly. Phonon exchange during fusion and dissociation reactions is predicted Second-order site-other-site reactions are predicted under conditions where the reactions at each site exchange phonons with a common phonon mode. The null reaction in which a dd-fusion at one site is coupled to 4He dissociation at another site is modeled. Coupled-channel equations are developed for the two-site problem, as an illustration of the application of the lattice resonating group method. We have proposed previously that there should exist compact state solutions of the coupled-channel equations, as the associated exchange potential can be attractive. Such states have been proposed to account for the Kasagi effect, and to provide a foundation for many of the anomalies that are seen in metal deuterides. Our analysis of the two-site system suggests so far has not yielded compact state solutions. Preliminary results for the many-site problem are presented, which leads to evidence in support of the stability of the compact states, and which leads to a new overall picture for the anomalies.
Hagelstein, P.L. Forward. in Tenth International Conference on Cold Fusion. 2003. Cambridge, MA: LENR-CANR.org.
Coauthors:The Tenth International Conference on Cold Fusion was held at the Royal Sonesta Hotel in Cambridge, about a mile from the Massachusetts Institute of Technology, August 24-29, 2003. More than 150 people registered for the conference. There were 113 abstracts submitted prior to the conference, and several talks were added during the conference. About 60 oral presentations were scheduled with 25 minutes allowed for most talks. All oral presentations were given in the main hall, and there were no parallel sessions. Abstracts were submitted for talks on excess heat and related topics, tritium, transmutation, nuclear emissions, theory, and a small number of other topics. . . .
Hagelstein, P.L. Resonant Tunneling and Resonant Excitation Transfer. in Tenth International Conference on Cold Fusion. 2003. Cambridge, MA: LENR-CANR.org.
Coauthors:Issues involved in the tunneling of deuterons in metal deuterides are considered in relation to experimental claims of anomalies in metal deuterides. From earlier studies, screening is thought to be similar to the case of molecular D2. Resonant tunneling has been advocated in the literature as a possible mechanism to achieve tunneling enhancements. We develop a two-level system for a piecewise constant potential model for resonant tunneling that matches the energy levels in the vicinity of a level crossing, arguing that such models are applicable for more general potential models. Resonant tunneling effects and dynamics, including acceleration due to coherence, are accounted for in the model. The model is extended to include relaxation effects, and it is found that one would not expect to find coherent effects associated with tunneling in the case of two deuterons in a metal lattice. We present a simple model for the transfer of excitation from a collection of deuterons to a collection of helium nuclei, a model closely related to resonant tunneling and also to new phonon-coupled SU(N) models under development. The excitation transfer models show coherent enhancements as well as collective effects.
Hagelstein, P.L. Thermal to Electric Energy Conversion. in Tenth International Conference on Cold Fusion. 2003. Cambridge, MA: LENR-CANR.org.
Coauthors:As research in the area of excess power production moves forward, issues associated with thermal to electric conversion become increasingly important. This paper provides a brief tutorial on basic issues, including the Carnot limit, entropy, and thermoelectric conversion. Practical thermal to electric conversion is possible well below the Carnot limit, and this leads to a high threshold for self-sustaining operation in Pons-Fleischmann type experiments. Excess power production at elevated temperatures will become increasingly important as we move toward self-sustaining devices and energy production for applications. Excess power production in heatproducing systems that do not require electrical input have an enormous advantage over electrochemical systems. Such systems should be considered seriously within our community in the coming years.
Hagelstein, P.L. Unified Phonon-Coupled SU(N) Models For Anomalies In Metal Deuterides. in Tenth International Conference on Cold Fusion. 2003. Cambridge, MA: LENR-CANR.org.
Coauthors:We present a systematic, but abbreviated, account of issues and models for anomalies in metal deuterides. To interact, deuterons must get close to one another, and we consider conditions under which this occurs and the ramifications. Within the general picture under discussion, anomalies are ultimately a consequence of phonon exchange that occurs when nuclear reactions take place in the solid state. We review the generalization of the resonating group method for reactions in vacuum to include solid state effects, and discuss implications for experiment. Phonon exchange in the case of a much simplified scalar Gaussian nuclear model is reviewed. The coupling of reactions at different sites is explored, and connections are made with recent experiments on alpha emission. The fastest site-other-site reactions are null reactions in which fusion reactions and their inverses are coupled. A consideration of these processes leads to the conclusion that compact states should be present stabilized by phonon exchange, and that these may be responsible for anomalies in recent beam experiments with metal deuterides. Energy exchange between nuclei and the lattice can be very efficient, according to results from idealized models for null reactions involving many sites. Aspects of excess heat production and other effects appear to be addressed by the new models.

Coauthors:Models based on phonon exchange for excess heat production in Fleischmann-Pons experiments are considered. In the case that sufficient phonon exchange occurs to stabilize intermediate states containing a neutral, then a model in which excitation is transferred from the D2/4He system to a strongly coupled quantum system made up of an oscillator (highly-excited phonon mode) and a Dicke system (ground state and excited state receiver nuclei) seem appropriate. We find that a coupled Dicke system and oscillator can support energy coupling in the case of strong coupling. We present evolution equations for resonant coupled Dicke systems, augmented with loss. An update is provided on phonon exchange in nuclear calculations.

Coauthors: Chaudhary, I.The absence of energetic particles commensurate with the energy produced is the single most notable feature of the Fleischmann-Pons experiment for theory, assuming that a new nuclear process is involved. We discuss briefly energy exchange between two-level systems and a low energy oscillator, concluding that spin-boson models augmented with loss are able to describe coherent energy exchange involving a large number of oscillator quanta. Since the coupling between deuterons and the lattice is weak, the excitation must be transferred to a different system with stronger coupling, in order to develop a simple model relevant for heat production. The resulting toy model can be used for simulation, and we describe briefly ongoing efforts to develop a computational model.

Coauthors: Melich, M. E., Johnson, R.Excess heat in the Flesichmann-Pons effect constitutes a new physical effect unlike other physical processes with which we are familiar. Many groups have proposed theoretical mechanisms to account for the effect, but at present none has been generally accepted. This motivates us to review what experiment tells us about theory. There exists a relatively large body of experimental results, and it is possible to connect many of these individual results to theoretical statements, which might then be used as the basis for the development of new theoretical models.

Abstract
The main issue before this conference can be stated as a simple question:
Question #1: Can large amounts of heat be generated at a significant rate by Pd/D interaction as announced by Fleischmann and Pons?
By now there have been many experimental results claiming to answer “yes” and which force us to take that possibility very seriously. As used here the “large amounts” are much larger than can possibly be explained by chemistry or metallurgy as known today. Up to now the only practical way of answering this question is by Pd/D calorimetry. . . .

Abstract
Measurements of electrolytic deuterium loading into Pd and Pd-Rh alloy cathodes and excess heat during electrolysis in 1M LiOD have been conducted simultaneously in closed cells with a fuel cell anode pressurized by deuterium gas. The excess heat up to 4-5W/Pd cc has been reproduced by using Pd rod cathodes from various sources. Excess heat increases with electrolysis current density higher than ca. 0.1-0.2 A/cm2, cathode overvoltage and D/Pd higher than 0.80-0.84, but its dependence on D/Pd or D/M appears to be specific to each cathode material in the region of high cathode loading, where the current density or overvoltage appears to be a more important parameter to control the amount of excess heat than the cathode loading.

Unusual nuclear transmutation reactions have been reported by Mitsubishi Heavy Industries (MHI). In their experiment, D2 gas permeates through a Pd complexes, which consists of a thin Pd layer, alternating CaO and Pd layers and bulk Pd. When they used sample Pd complexes with additional Cs on the surface, Pr emerged on the surface while Cs decreased after the sample was subjected to D2 gas permeation at 343 K and 1 atm for about one week. The elemental analysis was performed by X-ray photoelectron spectroscopy (XPS). This phenomenon was reproduced qualitatively in the present replication experiment.
We performed D-permeation experiments similar to the MHI’s experiment three times, and we confirmed the production of Pr. Pd complex samples were provided to us by MHI. The surface was electrolytically cleaned to remove hydrocarbons before depositing Cs. D2 gas was permeated through the Pd complexes at 343 K and 1 atm for about 5 days. Inductively Coupled Plasma Mass Spectrometry (ICP-MS) was performed to analyze the existence of the elements (Cs and Pr) and the mass distribution. The results showed the existence of Pr. And we also confirmed the existence of Pr by using fast Neutron Activation Analysis (NAA) in Fusion Neutronics Source (FNS) of Japan Atomic Energy Research Institute (JAERI).
As a result, we confirmed that the nuclear transmutation reaction, from 133Cs to 141Pr, was occurred. This transmutation suggests that the mass numbers and atomic numbers increase 8 and 4, respectively. The model of multi-body resonance fusion of deuterons proposed by A. Takahashi2 can explain this mass-8-and-charge-4 increased transmutation.

ABSTRACT
Conversion of deuterium to tritium in palladium has been clearly confirmed by the Arata-Zhang experiments. Endothermic element synthesis in Pd. and/or Ni layers due to high proton concentration, in analogy to stellar synthesis can be seen from the generation of very rare elements such as terbium. A convincing explanation is necessary. It was concluded phenomenologically that the reaction of the protons or deuterons by fusion or with the nuclei of the host metal occurs at a distance of about picometers with a reaction time of about megaseconds. It was noted that the Bohr radius rB of hydrogen atoms in a dielectric with refractive index n is changed to rBn2. such that with the electron concentration of the host metals a plasma refractive index of 0.076 results in a value of 3pm. In order to understand the subsequent dielectric modification of the ionization energy, we apply the model of depression of this energy by the Inglis-Teller effect for which a model with the best agreement with plasma experiments was presented before. For our model of the dielectrically shrunk picometer hydrogen atoms, the low ionization energies result in a reasonable relation between dielectric properties and the effective Debye length. Preference of the reaction at surfaces or interfaces between different host metals are due to the same reduction of the dielectric response as observed with surface plasmons. For the swimming electron layer theory, the spreading of the double layer for metal interfaces was discussed.

Coauthors:For summarizing theoretical papers of the ICCF9 conference, a short reminder should be given about some significant experimental results that can form a basis for a theory of low energy nuclear reactions (LENR). For a more historic view, the motivation for the Fleischmann-Pons experiment or the Preparata effect were well explained while-as an unusual view-L. Case reported that experiments may be understood by a simple chemical process involving catalytic surface properties. This could also explain why heat production happens in some cases and not in other cases. Contrary to this is the history of the observation of neutron emission from palladium compounds [1] or from deuterated palladium [2] that indicate nuclear processes. Today we have the significant result of Tian, Li et al [3] that the reaction of palladium wires after reacting with a hydrogen atmosphere during a current discharge, when the energy input was stopped and the gas evacuated, generated “heat after dead” for 43 hours producing about 3.6kW/cm3 or 13 keV/atom Pd . . .

Coauthors: Miley, G. H., Li, X. Z., Kelly, J., Osman, F.Since the appeal by Brian Josephson at the meeting of the Nobel Laureates July 2004, it seems to be indicated to summarize the following serious, reproducible and confirmed observations on reactions of protons or deuterons incorporated in host metals such as palladium. Some reflections to Rutherford’s discovery of nuclear physics, the Cockroft-Oliphant discovery of anomalous low energy fusion reactions and the chemist Hahn’s discovery of fission had to be included. Using gaseous atmosphere or discharges between palladium targets, rather significant results were seen e.g. from the “life after death” heat production of such high values per host atom that only nuclear reactions can be involved. This supports the earlier evaluation of neutron generation in fully reversible experiments with gas discharges hinting that a reasonable screening effect – preferably in the swimming electron layer – may lead to reactions at nuclear distances d of picometers with reaction probability times U of about megaseconds similar to the K-shell capture radioactivity. Further electrolytic experiments led to Low Energy Nuclear Reactions (LENR) where the involvement of pollution could be excluded from the appearance of very seldom rare earth elements. A basically new theory for DD cross sections is used to confirm the picometer-megasecond reactions of cold fusion. Other theoretical aspects are given from measured heavy element distributions similar to the standard abundance distribution, SAD, in the Universe with consequences on endothermic heavy nuclei generation, magic numbers and to quark-gluon plasmas.

Coauthors: Miley, G. H., Philberth, K.The discovery of nuclear fission by Hahn and Straßmann was based on a very rare microanalytical result what initially could not indicate the very complicated details of this most important process. A similarity is discussed for the low energy nuclear reactions (LENR) being proved from analogies of measurements of uranium fission. The distribution of the elements with uranium fission is similar to the element distribution with LENR. This was observed repeatedly and reproducibly with high density deuteron concentration in palladium. This discussion is specifically focussed to the Maruhn-Greiner local maximum of the distribution within the large-scale minimum if the fission nuclei are excited. The consequences of the complications in uranium fission are discussed in comparison with LENR with respect to the studies of a hypothetical fissioning compound nuclear reaction via a concluded element 306X126 with double magic numbers.

Abstract
A number of features of the presence of interstitial species in metals and alloys relevant to “solid state fusion” experiments are discussed. These include experimental evidence for very high virtual pressures under certain conditions, and the influence of promotors and surface blockers. Dislocation generation and motion can result from the large stresses accompanying composition gradients and phase transformations. Because of preferential segregation of interstitial species to dislocations, transport along dislocations can be much faster than through the bulk crystal, and dislocation motion can cause unusually rapid interstitial solute transport and both entry and emission from surfaces. Mechanical effects related to the presence of hydrogen often are sporadic and can have long delay times. It is possible that some of the same microstructural features and phenomena that are responsible for delayed mechanical behavior play an important role in the “solid state fusion” observations. Two dislocation mechanisms are presented that can produce transient local hyperloading.

Coauthors: Nix, W. D.Abstract. Mechanisms that are involved in the loss of capacity upon the cycling of electrochemical cells are discussed. The inherent instability of the electrochemical interface and the resultant geometrical changes are characteristic of electrodes in which the reactant is a pure element. On the other hand, decrepitation can play an important role in the case of polyphase electrodes in which significant changes in specific volume occur. A simple one-dimensional model is presented that shows the mechanism and the important parameters that are involved in particle fracture. It predicts that decrepitation will lead to a terminal particle size, as is found experimentally.

Coauthors: Czerski, K., Heide, P.
An overview of our experiments and their results concerning the electron screening effects in metallic environments are presented. The measurements of the reactions 2H(d,p)3H and
2H(d,n)3He were performed with an electrostatic accelerator at incident deuteron energies between 5 and 60keV at different self-implanted target materials. The resulting screening energy values are about one order of magnitude larger compared to gas target experiments and exceed significantly the theoretical predictions. A thorough investigation of the processes in the targets under ion irradiation shows that there are multi-parameter collateral effects which are crucial for the correct interpretation of the observed enhancements. They mainly originate from target surface contaminations due to residual gases in the vacuum as well as from inhomogeneities in the deuteron density distribution in heterogeneous targets. For the special situation of deuterium in the metallic environment an improved analysis method has been developed beyond the standard procedures. Experimental evidence for the influence of such effects and a mathematical model for their assessment are given and compared with the results of other groups. We also present a numerical model of the electron screening effect in metallic lattices based on an ab-initio Hartree-Fock simulation.

Coauthors: Czerski, K., Dorsch, T., Heide, P.Angular distributions and the neutron-proton branching ratio of the mirror reactions 2H(d,p)3H and 2H(d,n)3He have been investigated using different deuterized metallic targets at projectile energies ranging from 5 to 60 keV. Whereas the experimental results obtained for Al, Zr, Pd and Ta targets do not differ from those known from gas-target experiments, an enhancement of the angular anisotropy in the neutron channel and a quenching of the neutron-proton branching ratio have been observed for Li and Sr targets at deuteron energies below 20 keV. Both effects can be explained assuming an induced adiabatic polarization of the reacting deuterons in the crystal lattice.

Coauthors: Czerski, K., Heide, P., Ruprecht, G., Targosz, N., Zebrowski, W.Recent measurements of the reaction 2H(d,p)3H in metallic environments at very low energies performed by different experimental groups point to an enhanced electron screening effect. However, the resulting screening energies differ strongly for diverse host metals and different experiments. Here, we present new experimental results and investigations of interfering processes in the irradiated targets. These measurements inside metals set special challenges and pitfalls that make them and the data analysis particularly error prone. There are multiparameter collateral effects that are crucial for the correct interpretation of the observed experimental yields. They mainly originate from target surface contaminations owing to residual gases in the vacuum as well as from inhomogeneities and instabilities in the deuteron density distribution in the targets. To address these problems an improved differential analysis method beyond the standard procedures has been implemented. Profound scrutiny of the other experiments demonstrates that the observed unusual changes in the reaction yields are mainly due to deuteron density dynamics simulating the alleged screening energy values. The experimental results are compared with different theoretical models of the electron screening in metals. The Debye-Hückel model that has been previously proposed to explain the influence of the electron screening on both nuclear reactions and radioactive decays can be clearly excluded.

Abstract
A series of measurements have been performed on a thin sheet of Pd in D2 gas atmosphere with an electric field applied across its length. The results in terms of correlation between the average loading ratio near the cathode and in the middle of the sheet are reported: they indicate that under particular conditions the application of the electric field succeeds to shorten the loading time and to obtain local D/Pd ratios higher than the average value.

Deuteron implantation experiments on Ti and Pd foils have been made for the examination of the “cold” deuteron fusion reaction. In the center of a target chamber fitted to a 300 keV deuteron accelerator, a Ti or Pd foil sample was set to face toward 3 nsec pulsed deuteron beams collimated with a 3 mm diameter aperture. A Si-SSD was placed behind the foil to detect high energy charged particles emitted from the foil by the supposed deuteron fusion reactions.
In the 243 keV deuteron implantation experiments for 3-20 μm Ti and 5-22 μm Pd foils, unusual counts and peaks were measured in the energy region higher than the proton peak due to the well-known D-D reaction. And from the energy loss measurement with the screen foil in front of the Si-SSD, some of the unusual high energy peaks were found to be helium, though the original reactions are not identified. These helium peaks and unnatural counts are difficult to explain and might have something to do with the multibody fusion reactions proposed by A. Takahashi. More elaborate experiments with more detailed measurement such as correlated particle measurement should be necessary for confirmation of the multibody fusion reaction.

A compact scheme of non-thermonuclear fusion is presented. Hydrogen ions are implanted directly from nonthermal discharge plasma or ion source into a surface of liquid Li metal at a buffer energy of a few tens keV where nuclear stopping occurs. The ions interact with Li atoms or mixed element atoms which are not being internally excited and tend towards the formation of united atoms at the minimum Gibbs free energy point. This leads to the enhanced rate of non-thermonuclear fusion of hydrogen ions due to cohesion in the liquid metal.

In the electrolysis experiment, upper gas of the electrolysis cell was analyzed using a Quadrupole Mass Analysis System (Q-MAS). Significant amount of helium-4 was detected without neutron emission in several experiments and in one of these experiments, the amount of helium-4 atom in the released gas from the palladium cathode was 8.1x1016 atoms. Under electron beam irradiation to highly D-loaded palladium, anomalous spectra were taken in X-ray measurement. In the experiments using deuteron beam and TiDx, responses which suggested 3D multi-body fusion were taken and the reaction rate of which was increased compared to the D(d,p)T reaction rate, below 100 keV. This result may reflect the coherent effect of the solid state in the reactions. From the results of the experiments using proton beam and TiDx, peaks which suggested 3D multi-body reaction were detected with high reproducibility. Moreover, high energetic protons having 17-20 MeV emitted kinetic energy which suggested H-D-D three-body coherent fusion were also detected.

We report here the experimental results suggesting the occurrence of multibody nuclear reactions in metal deuterides under ion-beam irradiation and electrolysis. A meaningful increase of helium-4 was observed during electrolysis with the Pd-D2O system, while neutron emission was not observed. The D+D+D fusion, 3D→t+3He+9.5 MeV, has been observed repeatedly in deuteron-beam irradiation experiments with a TiDx target. On the other hand, in proton-beam experiments with TiDx, H+D+D-fusion: H+D+D→p+4He+23.8 MeV was observed. Considering this result, it seems that the 3D reaction occurred between two deuterons trapped closely in TiDx and an incident particle of deuteron. . . .

Coauthors: Itoh, T., Gotoh, N., Toyoda, I.We developed a new type of experimental apparatus for simultaneous measurement of excess heat and nuclear products with intent to induce continuous nuclear reactions in D2 Pd system. It consists of two parts: an electrochemical cell for calorimetry, and a vacuum chamber for nuclear measurement. Deuterium atoms flow continuously from the electrochemical side to the vacuum side through a palladium plate, and we might expect that nuclear reactions last for a long term in the system, since it is considered that diffusion process of deuterium atoms in palladium is important to induce nuclear reactions.

Abstract
A new type of experimental apparatus is developed to induce nuclear reactions by continuous diffusion of deuterium. Ti atoms, which cannot be explained by contamination, were detected on the surface where deuterium atoms passed through on Pd cathodes after electrolysis. A multi-layer cathode (Pd/CaO/Pd) is introduced based on an EINR (Electron Induced Nuclear Reaction) model. Excess heat generations and x-ray emissions were observed for all the cases we tried by the multi-layer cathodes. 57Fe/56Fe ratio of Fe atoms detected on the multi-layer cathodes is anomalously larger than natural

Coauthors: Itoh, T., Sakano, M.Two kinds of experimental methods have been designed to induce nuclear reactions in the Pd-D system. One is the D2 gas diffusion method, and the other is the electrolysis diffusion method. A common feature of the methods is to cause continuous diffusion of deuterium through a multi-layer Pd that contains low work function material (CaO, TiC, YzOs, etc.). Time dependence of nuclear products (Mg, Si, S, F, Al) were observed by the D2 gas diffusion method, in which the products were analyzed WITHOUT taking the multi-layer Pd out of the apparatus. The time dependence of the products was reproduced qualitatively. The 33S/32S ratio of the products was one order larger than that of natural abundance. Fe isotope ratio anomaly of the multi-layer Pd obtained by the electrolysis diffusion method was confirmed by SIMS and TOF-SIMS. Si powder products detected after electrolysis amounted to 0.057g, and its isotopic composition was anomalous.

ABSTRACT: The present invention produces nuclide transmutation using a relatively small-scale device. The device 10 that produces nuclide transmutation comprises a structure body 11 that is substantially plate shaped and made of palladium (Pd) or palladium alloy, or another metal that absorbs hydrogen (for example, Ti) or an alloy thereof, and a material 14 that undergoes nuclide transmutation laminated on one surface 11A among the two surfaces of this structure body 11. The one surface 11A side of the structure body 11, for example, is made a region in which the pressure of the deuterium is high due to pressure or electrolysis and the like, and the other surface 11B side, for example, is a region in which the pressure of the deuterium is low due to vacuum exhausting and the like, and thereby, a flow of deuterium in the structure body 11 is produced, and nuclide transmutation is carried out by a reaction between the deuterium and the material 14 that undergoes nuclide transmutation.

ABSTRACT
Observation of low energy nuclear reactions induced by D2 gas permeation through Pd complexes, which consist of a thin Pd layer, alternating CaO and Pd layers and bulk Pd, is described. The Pd complex was located in a vacuum chamber and the elemental analysis was performed using an X-ray photoelectron spectroscopy (XPS) apparatus mounted on the chamber. When Cs was added on the surface of a Pd complex, Pr emerged on the surface while Cs decreased after the Pd complex was subjected to D2 gas permeation at 343K and 1atm for about one week. In the case of adding Sr on the surface, Mo emerged on the surface while the added Sr decreased after D2 permeation for about two weeks. All the phenomena were reproduced qualitatively. The isotopic composition of the detected Mo exhibited characteristics indicating an isotopic abundance of Sr rather than the natural abundance of Mo

Observations of low energy nuclear reactions induced by D2 gas permeation through Pd complexes (Pd/CaO/Pd) were presented at ICCF-9 and in a paper published in the Japanese Journal of Applied Physics (JJAP). When Cs was added on the surface of a Pd complex, Pr emerged on the surface while Cs decreased after the Pd complex was subjected to D2 gas permeation. When Sr was added to the surface, Mo emerged while the Sr decreased after D2 gas permeation. The isotopic composition of the detected Mo was different from the natural abundance.
In this paper, recent progress of our research is described. The detected Pr was confirmed by various methods such as TOF-SIMS, XANES, X-ray Fluorescence Spectrometry and ICP-MS. Analysis of the depth profile of Pr indicated that a very thin surface region up to 100 angstroms was the active transmutation zone. Many experimental results showed that the quantity of Pr was proportional to the deuterium flux through Pd complex. The cross section of transmutation of Cs into Pr can be roughly estimated at 1 barn if we consider the deuterium flux as an ultra low energy deuteron beam.

Coauthors:We have been studying low energy nuclear transmutations induced by D2 gas permeation through Pd complexes (Pd/CaO/Pd). We presented experimental results at ICCF9 and ICCF101-3. In this paper, we report recent progress. Transmutations of Ba into Sm were observed in two cases: with natural Ba on Pd complex samples (a definite result), and with mass 137-enriched Ba (probable). In these experiments, the atomic mass increase was 12 and atomic number increase was 6. One of our experimental apparatuses was carried to SPring-8, which is the world’s largest synchrotron radiation facility, located at Hyogo prefecture in Japan. Pr was confirmed several times by XRF at SPring-8. Some experiments were done to explore physical structure of the CaO layer. According to a D+ ion beam bombardment experiment performed at Tohoku University, the deuterium density of our Pd complex is one order larger than normal Pd. When we replaced CaO with MgO, we did not obtain any positive results. These results shed light on the role of the CaO layer in the Pd complex.

Transmutations of Ba into Sm were observed both when natural Ba was applied to the Pd complex samples, and when mass 137-enriched Ba (monoisotopic Ba) was applied. The mass distribution of Sm that we obtained depended on the starting isotopic distribution of Ba.
One of our experimental apparatus was carried to SPring-8 for the purpose of in-situ measurement, and we obtained a Pr signal using the X-ray Fluorescence method.
According to a D+ ion beam bombardment experiment performed at Tohoku University, the deuterium density of our Pd complex is one order of magnitude larger than normal Pd.

Coauthors: Itoh, T., Sakano, M., Yamazaki, N., Kuribayashi, S.In-situ measurement of transmutation of Cs into Pr was performed, and the surface distribution of Pr was investigated using XRF (X-Ray Fluorescence spectrometry) at SPring-8, a large synchrotron x-ray facility. The in-situ measurement indicated that Pr emerged and Cs decreased at some points after D2 gas permeation, though any Pr cannot be observed before D2 gas permeation at all the points on the Pd complex surface. Using small size X-ray beam in 100- and 500-micrometer squares, we obtained 2 dimensional XRF spectra for three permeated samples, from which we detected Pr. Pr was detected again by the two small x-ray beams as expected. The amount of Pr varied greatly at different locations of the Pd surface, however, a clear correlation between surface structures and distribution of Pr has not seen up to now. Experimental results suggest that nuclear transmutations do not occur uniformly but some uncertain factors, presumably condensed matter effects in the present Pd/D/CaO system, have a large effect on the rate or the process of the reactions.
