Evidence of Anomalous Tritium Excess in D/Pd Overloading Experiments

Measurements of Tritium have been performed, using a very low background and accurate instrumentation, on electrolytes before and after Deuterium absorption in Palladium wires. Tritium was always present in the electrolytic cells, having long and thin Palladium wires (carefully degassed) as cathode and Platinum wire as anode, because "normal contamination" of deuterated liquids. Two different kinds of electrolytes were used (unusual, for several aspects, to conventional ones adopted in Cold Fusion experiments): the first one was composed by heavy water in DCl acidic environment (pH=4.5) with the addition of Strontium (and Mercury) salts at micro-molar concentration, the second one was composed by heavy ethyl alcohol--heavy water solution (concentration ratio about 11:1), acidic environment (DCl+D2SO4), with the addition of Strontium and Mercury concentrated as before.We have found anomalous Tritium production (at large statistical significance) only when the achieved loading ratio (D/Pd) was quite large (about 0.95) and several loading/deloading cycles had been performed.
