Recent experiments provided evidence of piezonuclear reactions occurring in condensed matter during fracture of solids, cavitation of liquids, and electrolysis. These experiments were characterized by significant neutron and alpha particle emissions, together with appreciable variations in the chemical composition. A mechanical reason for the so-called Cold Nuclear Fusion was recently proposed by the authors. The hydrogen embrittlement due to H atoms produced by the electrolysis plays an essential role for the observed microcracking in the electrode host metals (Pd, Ni, Fe, etc.). Consequently, our hypothesis is that piezonuclear fission reactions may occur in correspondence to the microcrack formation. In order to confirm the first results obtained by Co-Cr and Ni-Fe electrodes, electrolytic tests have been conducted using 100 % Pd at the cathode. As a result, relevant compositional changes and traces of elements previously absent have been observed on the Pd and Ni-Fe electrodes after the experiments and significant neutron emissions were observed during the test.
