Brief Explanation of Experimental Data Set on Excess Heat and Nuclear Transmutation in Multiplly Nanocoated Ni Wire

Experimental data of excess heat generation and nuclear transmutation obtained in Ni wire multiplly nano-coated with Pd and a compound of B, Sr, Ba and Th at up to 900 degC have been analyzed using the TNCF model. The Ni wire is 50 μm in diameter and 82 cm long. The coating is made of Pd and the compound about 50 times resulting in a surface layer of about one μm thick. The maximum excess energy Qmax is 1800 W/g of the Ni wire. There have occurred various nuclear transmutations. The most notable results are enumerated as follows: (1) Elements Ti, Cr, Co, As, Ir, and Tl have increased. (2) B, Sr, Pd and Ba have decreased. (3) Fe and Ni have not showed remarkable change. (4) In the case of B, Sr and Ba, the rates of the decrease are larger for lighter isotopes. (5) 105B/115B ratio decreased over 14%. (6) 10546Pd decreased about 5% and 10246Pd increased about 9%. These data have been analyzed using the TNCF model successfully applied for explanation of various experimental data sets over the past 15 years. We can estimate the parameter of the model nn using the data for 105B and 10546Pd as follows; nn = 1.3x109 cm'3 (by the decrease of 105B) and nn = 2.5x1011 cm'3 (by the decrease of 10546Pd). These values show the situation in the experiment belong to a range of fairly large value of the parameter where we can expect the nuclear reactions by a single neutron and also a n-p cluster. The excess heat generation of 1800 W/g at its maximum has been investigated using the value of nn estimated above and a formula for the excess energy is induced. Assuming the surface layer of 1μm thick is made of Pd only, for illustrative purposes, we have obtained Qav about 1% of the observed maximum one. If the average value of the excess energy is about 10% of the maximum, the discrepancy is about one order of magnitude. If we know the correct composition of the surface layer, the calculated value of Qav will increase a little. The nuclear transmutation of several elements confirmed by the experiment is qualitatively explained assuming the single neutron absorption by elements in the surface layer. The decrease of Ru might be explained by a single n-p cluster absorption.
