In the Pd/H2O electrolysis system, new elements, Mg, Cl, Fe, Al, Ca, K, and others, absent in the original system have been observed by Bockris and Minevski (Infinite Energy 1995-96;5 and 6:67) in the surface region of the metal hydride PdH, cathode with a thickness of 2 mu m up to 10% of the matrix element Pd. The data is analyzed using the TNCF model to give consistent explanation of these new elements by fission of nuclei Formed from Pd isotopes in cathode by absorption of a thermal neutron. The parameter of the model, n(n) is determined to be n(n) = 3.0 x 10(11) cm(-3) consistent with the values determined by other experimental data in various events of Cl; phenomenon.
