摘要:
Gas loaded D/Pd and H/Pd rods (1 mm diameter) were used to investigate correlated thermal and nuclear effects. Simultaneous measurements were made of gas pressure, electric current, voltage drops, rod and chamber temperature, and neutrons. D/Pd and H/Pd ratios were monitored by resistance changes in the rod segments. Two deuterium runs (totaling 3000+ hours), one hydrogen run (nearly 1000 hours), and background runs (nearly 2000 hours) have been completed. two neutron bursts were recorded in the first deuterium experiment. No bursts, but periods of increased activity, were observed in the second deuterium run. No increased activity was observed in the hydrogen experiment. Accurate agreement with Poisson counting statistics was found in the background and hydrogen runs. Neutron bursts observed in the first deuterium run exceeded, by several orders of magnitude, the Poisson prediction. A slight resistance increase in one rod segment was observed during one of the neutron bursts. No simultaneous increase in rod temperature was observed. Several potential triggering mechanisms were tried. Further experiments will examine an observed possible resonance‐like effect.
