Studies on Behavior of Deuterium and Hydrogen In Palladium

The absorption, reserve, diffusion of deuterium and hydrogen in palladium, and the positron lifetime of palladium during electrolysis are investigated by hydrogen permeation method and positron annihilation spectroscopy. The results show that the electrochemical behavior of deuterium is almost the same as that of hydrogen, but the amount of deuterium reserved in palladium is lightly less than that of hydrogen and the diffusion coefficient of deuterium is slightly greater than that of hydrogen. The positron lifetime in palladium after electrolysis is increased by 10. 5%. The behavior similarity of deuterium and hydrogen and the possibility of "cold nuclear fusion" are disscussed.
