Experimental Study on Correlation between Excess Heat and Nuclear Products by D sub(2)O/Pd Electrolysis

Using two electrolysis systems based on D sub(2)O/Pd electrolysis, experimentalsearches were tried to find correlation between excess heat and possible nuclearproducts (neutrons, X-rays, tritium and helium). One was the open electrolysis system with twin cells to study correlation between excess heat, X-rays andneutrons. The other was the closed electrolysis system to study correlationbetween D/Pd ratios, excess heat, neutrons and helium. No very clear correlation between excess heat and any nuclear products have been observed, butseveral marginal-level data were obtained to show helium-4 production whenexcess heat were observed in the closed electrolysis system. In few cases bythe open electrolysis experiments, clear excess heat was observed with no visible increases of characteristic X-rays and neutrons over back ground. Burstevents of soft X-rays and neutrons were observed in few cases, being independent of excess heat productions.
