Complexity in the Cold Fusion Phenomenon

The cold fusion phenomenon (CFP) in Solid State-Nuclear Physics (SSNP) or Condensed Matter Nuclear Science (CMNS) occurs in composite systems with regular arrangements of host nuclei (C, Ti, Ni, Pd, etc.) and intervening hydrogen isotopes (H, D). We have figured out several features of experimental data sets in the CFP showing characteristics of many-particle effects such as (1) the inverse-power law of excess power generation [1, §2.12], (2) the stability effect of transmuted product nuclei (elements) [1, §2.11], and (3) bifurcation of intensity of cold fusion (CF) effects [2]. The systems (CF materials) where occurs the CFP have common properties with those where observed complexity experimentally which has also been investigated theoretically with computer simulation. We have microscopically analyzed CF materials to find out causes of events [1, Chap. 3, 6] resulting in the above-mentioned many-particle effects and explained the occurrence of the complexity in the CFP [3]. In our analyses, it was shown that the adjustable parameter nn appeared in the TNCF model which has been successful to give several quantitative relations between numbers of reactions Nx for events X in accordance with experimental data sets seems to be useful as a parameter governing the equation describing dynamical processes resulting in complexity. Using the parameter nn as one specifying recursion relations of the cold fusion phenomenon (CFP), classical experimental data sets such as those by Fleischmann et al. (1989), De Ninno et al. (1989), and McKubre et al. (1993) have revived as typical examples showing some phases of the CFP related with complexity. Thus, the controversial questions such as reproducibility
