Abstract

A beam of Argon ion laser (λ = 488 nm and P = 40 mW) was used to irradiate some palladium deuterides with different deuteron loading ratios in a D/Pd gas-loading system (19 different loading ratios ranging from 0 to 0.77). The results showed that there was a maximum excess heat of about 287 J within an hour in the system when the loading ratio was about 0.65. This corresponds to 2.6×103 eV/atom D or 1.7 ×103eV/atom Pd. The results indicate that the proper ratio in the Pd lattice matching a suitable triggering power may be the key factor to excess heat production.
