THINKING ABOUT THE DEVELOPMENT OF COLD FUSION RESEARCH^{^*}

Makoto Okamato^{**} (Tokyo Institute of Technology)

Professor Hideo Kozima is a scientist who specializes in physics of matter. Since he usually takes a cool view of things, I can hardly imagine what led him to start the study of the mysterious world of cold fusion.

The phenomenon with earthly nomenclature “cold fusion” aroused considerable interest in various fields, resulted in criticism from the researchers consists of from individuals to people who work for public institutions. Professor Kozima must have been observing the progress calmly with the viewpoint of cool-headed scientists in the uproarious secular world.

Prof. Kozima showed up in this mysterious world in the phase most people had lost interest and were seeking other concerns. He may have found pleasure in revealing one of new phenomena, which have been much easily denied and disappear in those days. Science in the latter half of the 20th century is overwhelmed by mammoth-project experiments. Each scientist in the project is forced to conduct his study on the bases of such experiments, which prevents the scientists from developing unprecedented conceptions. Under these circumstances, Prof. Kozima was probably enchanted with the study of cold fusion as the most mysterious phenomenon.

Prof. Kozima, who established the solid foundation beyond his special domain, has analyzed the experimental data sets of this phenomenon with care and pursued investigations to find some physical clues. The book shows his thought processes. It is quite hard to select a theme worthy of study in this phenomenon. That is because there exist various approaches to the theory. There have been seen data full of variety including some unfinished poor theses and reports until now. I have long abandoned my efforts to find a theme. He completed the book because of his enthusiasm to establish a system in this confusion. Through his analysis he is trying to consolidate the various results presented as experimental truth and explain them theoretically. He selected the objects of the study by his scientific sensibility. However, I have to add that my viewpoint is not always the same as that of Prof. Kozima's.

Prof. Kozima is also proficient in Russian, often attends the Russian Conference, and is well informed on the studies in Russia and surrounding countries. The description of the researches in these countries introduced in this book is particularly useful as valuable materials for research. The last material, which is referred to in the book, is the paper published at the ICCF6 held in Toya, Hokkaido in the middle of October 1996. Since then some study groups have been developing the related studies based on scientific thoughts and methods. Prof. Kozima shows his own accomplishment, which isn't necessarily a common concept among the related research scientists. I can imagine that Prof. Kozima is now concentrating his efforts on another new paper in his quiet office at Shizuoka University. Finally I wish Prof. Kozima's devoted labor would be a key to resolve the confusion in this mysterious phenomenon.

**{Dr. Makoto Okamoto died of lung cancer on May 4, 1998 at his age of 60 as a Professor of Tohoku University where he moved to in April, 1997. He was a heavy smoker and used to tell that every smoker suffers not always from a lung cancer. Really, it is a matter of probability or qualitative reproducibility if one of smokers suffers from lung cancer or not, as a problem of statistics. I have to say, however, the death of Dr. M. Okamoto was too early and sad unexpected but definite event for me and for CF research community. I would like to express my condolences to Dr. M. Okamoto in heaven on his bereavement. }

PEFACE–ENGAGING IN CREATION OF A NEW SCIENCE-

Hideo Kozima, Shizuoka University

In the middle of April 1989 I received two papers from Dr. Tsutomu Tanaka*{}. He assisted me in making this English version by translating Chapters 1 to 5.}, a graduate of our laboratory, who was a doctoral student at the University of Wisconsin at that time. These were copies of preprints by M. Fleischmann and S. Pons in University of Utah and by S.E. Jones et al. at Brigham Young University. Those preprints of papers submitted to scientific journals had been rapidly faxed around the world and Dr. Tanaka kindly sent copies to me in Japan. This was quite different from the usual scientific information, but I think the news about the discovery of high-temperature superconductors which had shocked the scientific world about a year before somewhat had prepared us for paradigm shifts.

I was excited when I read the preprints even though newspaper articles had prepared me a couple weeks earlier. That memory still remains vividly in my mind.

*{Now in Applied Materials, Inc., USA

I decided to check the results obtained by Jones et al., which seemed as if they would be simpler to replicate than those of Pons and Fleischmann. I asked radiochemists Professor K. Hasegawa and Dr. H. Suganuma of Laboratory of Radiochemistry and electrochemist Mr. S. Oe of Department of Chemistry to cooperate with me in the experiment. Mr. Oe had a small palladium plate, a remnant of materials used in an experiment done many years ago. A neutron survey meter was borrowed from Chubu Electric Power Co. Heavy water was bought for 15,000 yens for 100 ml. As an electrolyte we had to use a simple compound LiOH instead of a complex mixture containing several compounds, as recommended in the Jones paper.

During the experiment, with a current ～ 200 mA (～ 4 mA/cm^{2}) and voltages of 20 ～ 30 V with a Pd 5 × 5 cm^{2} cathode, we observed neutron emissions of about twice the background level (1 ～ 2 counts per 10 minutes) after about 6 to 7 hours. Dr. Suganuma searched through the Chemical Abstracts papers for relevant information and found papers published in 1926 ～ 1927 by F. Paneth et al.

This was my first encounter with the cold fusion phenomenon.

Our experiment did not continue long since the Pd plate was exhausted after several 8-hour runs. It deformed and swelled, and then did not show any further excess neutron emissions. We tried a new Pd plate, which appeared different in color and shine, but it produced only background neutron counts.

The Third International Conference on the Cold Fusion (ICCF3) was held in Nagoya, Japan in October 1992. The Conference has been held every year or two since 1990. The first was held in Salt Lake City in March 1990, the second in Como, Italy in June 1991. Unfortunately I had no detailed information about the first two conferences or the data that was presented, so the conference in Nagoya was a revelation to me.

There was great enthusiasm for a new science that was just being born. There was, of course, much criticism of the experimental data presented at the conference, but we knew we had to tolerate some inevitable errors. An impressive scene that will never forgotten was when Professor Kodi Husimi (a former Head of the Plasma Laboratory, Nagoya University and a former President of the Science Council of Japan) gave a short speech at the reception where he expressed his enthusiasm for the new science, saying that scientists in this hall had the true scientific spirit.

The Proceedings of this Conference {\it Frontiers of Cold Fusion}, edited by Professor H. Ikegami, and published immediately after the Conference, has been a Bible to me. The data published in these Proceedings are a treasured resource of the cold fusion phenomenon. From my understanding of physics and my preliminary calculations done in 1989, it seemed to me that some agents must catalyze the cold fusion phenomenon.

This thought was supported by a lecture of Professor V.I. Ginsburg of Lebedev Institute of Physics, Russian Academy of Science, at Nishina Symposium of Riken*{} in October 1991. This was in commemoration of the centenary of the birth of the late Dr. Yoshio Nishina, the founder of atomic physics in Japan. Dr. Ginzburg explained that it is necessary to use a phenomenological approach for investigating the high-temperature superconductor phenomenon in its present stage of investigation.

*{The Institute of Physical and Chemical Research, Japan}

His confidence in his opinion was based on the brilliant tradition of Russian science, which has provided excellent models in physics history, such as two-fluid model of super-fluidity and Ginzburg-Landau theory of superconductivity.

At the Fourth International Conference on the Cold Fusion (ICCF4), held in Maui, Hawaii, in December 1993, I presented a paper, "Trapped Neutron Catalyzed Fusion of Deuterons and Protons in Inhomogeneous Solids," which had been developed a couple of months before the Conference. The cold fusion phenomenon data went round and around in my brain and finally I saw pieces of the puzzle coming together which might explain the cold fusion phenomenon.

The Kamiokande experiment, performed in a laboratory about 1000 m underground in Kamioka, Gifu, Japan in cooperation with Prof. S.E. Jones and researchers from The University of Tokyo, gave me an important hint. The Kamiokande data showed that there was no effect without background neutrons. Background neutrons have thus become a key agent of my model.

One important aspect of the cold fusion phenomenon is the poor reproducibility, or even we can say, irreproducibility. This irreproducibility had many critics denying the cold fusion phenomenon itself. When I talked with researchers engaged in this field, I heard that almost all of them have had the experience of obtaining positive results, but with poor reproducibility. This was most puzzling. If I had not obtained my initial positive results, I probably wouldn't have persisted investigating this curious new phenomenon as strongly. Thus, I attacked the problem of irreproducibility with my model, using the background neutrons as a catalyst. It is well known that atomic processes in materials are not yet fully understood.

I studied physics in Graduate School under Professor Toshinosuke Muto of The University of Tokyo. He was a rare Japanese physicist who worked both in solid state physics and in nuclear physics, claiming that all physics is one. In his laboratory, Saturday Seminar was open for scientists in both solid state and nuclear physics. I had chosen the solid state physics in the Graduate School but listened to presentations both in the solid state and nuclear physics in the Seminar, so I'm comfortable with both fields.

To start the construction of a model using the idea of thermal neutrons as a catalyst I asked the help of my friends and acquaintances. Dr. K. Sasaki of JAERI**{} helped me in neutron physics. Dr. M. Koike of Kakuken**{} and Dr. K. Kaki of our department helped me in nuclear physics. Professor T. Yoneyama helped me in elementary particle physics. Professor T. Ishidate was most interested in the idea and encouraged me through the work.

It is a common experience for many that a change of the point of view makes the scenery very different. It is the same in scientific research, as is well known with the example of the Copernican revolutionary the view of the universe. If we assume an existence of thermal neutrons in an appropriate material, almost all the riddles of the cold fusion phenomenon disappear: the fact that there was no excess heat generation in Ti system, but neutrons was explained by such a long decay distance of gamma ray in it as 8 cm compared with 2 cm in Pd. The excess heat-neutron anomaly could be explained by strong capture of neutrons in certain materials. The generation of ^{4}He could be explained easily by n - ^{6}Li and t - d reactions. Thus, the cold fusion phenomenon occurs not only in a deuterium system but also in a protium system, which was considered dubious even by the cold fusion researchers at that time.

The irreproducibility could be explained by the variable nature of atomic processes producing the optimum conditions for neutron trapping. These forecasts have been revised after a careful examination of the experimental data and the conditions controlling the events in the cold fusion phenomenon.

The idea of the neutron band in a crystal was in my mind when I was preparing my paper to present at ICCF5 held in 1995, in Monte-Carlo, Monaco. The trapping of neutrons, the lengthening of decay time of neutrons, and possible reactions of neutrons with other nuclei are necessary conditions for my so-called TNCF model to explain various events in the cold fusion phenomenon. About the first condition, trapping, the neutron band can give a hopeful mechanism to trap neutrons in a solid surrounded by another with a different band structure.

By the end of 1995, an answer to the second condition, the lengthening of the neutron decay time, was found. The idea of the neutron affinity of nuclei was hit upon in analogy with the electron affinity of atoms. If there are trapped neutrons in a solid and if the neutron affinity of nuclei in the solid is positive, the neutron is rather stable and tends to remain there rather than to decay into a proton and electron (and neutrino).

It should be noticed here that this stability of a trapped neutron against the beta decay is not the same as the stability against fusion with one of lattice nuclei interacting with it.

The third condition mentioned above, reactions with other nuclei, relates with this interaction of trapped neutrons and one of lattice nuclei.

This interaction was assumed to explain nuclear products from the beginning of the model's formulation; the trapped neutrons become unstable due to their excitation and perform ordinary nuclear reactions with any nucleus causing the excitation. These assumptions on the nature of the trapped neutrons are formulated as basis for the TNCF model.

The TNCF model was formulated in the autumn of 1995, though some revisions have had to be made to fit the model to new experimental data. The essential point of the model is that it includes only one adjustable parameter, with some premises about properties of the trapped neutrons. Using the model, various experimental results obtained in various systems have been analyzed, and all give a consistent explanation of the results using an adjustable parameter \enuenu between 10^{8} ～ 10＾{13} cm＾{-3}. At ICCF6 in 1996 in Hokkaido, Japan, those results were presented. The new data presented at ICCF6 by many careful researchers from around the world were immediately analyzed using the TNCF model and the results were published in several journals. At ICCF7 held in 1998, in Vancouver, Canada, the most recent version of the TNCF model was presented.

This book is a result of our work during these nine years, including a preliminary period from 1989 to 1995. Most of the material in this book has been developed during the last three years. There still remains the job of providing the microscopic support for the TNCF model, which could take several years.

Meanwhile, it should be helpful to experimentalists and theoreticians to have a one-volume review of the reported experimental results and an analysis using a proposed model, even though only about 50 experimental results have been analyzed using the model. We can draw a picture of a new science \haihun solid state-nuclear physics \haihun based on the discovery and development of the cold fusion phenomenon.
