Kozima’s Cold Fusion Research Laboratory was established by Dr. Hideo Kozima, Professor Emeritus at Shizuoka University, in April 1999 with his collaborators mainly graduates of Shizuoka University to promote researches in cold fusion phenomenon (CFP).

Cold Fusion Phenomenon（CFP）means nuclear reactions and accompanying events occurring in solids with high densities of hydrogen isotopes in ambient radiation.

Researches of CFP in CFRL is based on modern physics especially quantum mechanics of solids and nuclei.

A model (the trapped neutron catalyzed fusion (TNCF) model) was proposed based on characteristics of experimental data of CFP and used to analyze more than 60 experimental data sets. Results of these analyses until 1998 were summarized in a book “Discovery of the Cold Fusion Phenomenon – Development of Solid State-Nuclear Physics and the Energy Crisis in the 21^st Century” (1998) Works after the publication of this book are published in papers presented at several Conferences and published in several Journals.

In the process of researches in Portland State University supported by the New York Community Trust and the Professor Development Fund for part-time faculty of PSU, a new development in the model was performed to establish the neutron drop model which made successful explanation of nuclear transmutations with large changes of mass and proton numbers.

A news letter, The CFRL News, has been published almost monthly to communicate with CF researchers and friends from July of 1999.

     The TNCF model (Trapped Neutron Catalyzed Fusion model) is a phenomenological model with a single adjustable parameter that was applied to CFP and given unified explanation for them. Success of the model to give unified explanation of various events in CFP shows the premises assumed in the model have some physical reality.

The Neutron Drop Model is based on the new quantum mechanical knowledge of nuclear physics about exotic nuclei with large excess of neutron number over proton number and solid state physics about extended wave functions of proton and deuteron in transition-metal hydrides and deuterides. These factors made possible realization of such a new neutron states in these materials as the super-nuclear interaction between different lattice nuclei and then the neutron valence band which has accumulation of neutrons at surface/boundary regions. The accumulation was one of prefaces assumed in the TNCF model.

These works have given new insights into quantum mechanical investigations of the premises assumed in the TNCF model and also into physics of low energy neutrons in solids with high-density hydrogen isotopes.

Recent works in CFRL is centered on the complexity in CFP a face of it was discovered in the investigation of the stability effect in nuclear transmutation and of the inverse power law for occurrence of events in the CFP.
