Deuterated palladium at temperatures from 4.3 to 400 K and pressures to 105 kbar: Search for cold fusion

We have studied a sample of deuterated palladium at pressures up to 105 kbar and temperatures from 4.3 to 400 K in an effort to detect cold fusion. A [D]/[Pd] concentration of 1.34±0.1 was achieved. No evidence of cold fusion was found with a limit of 2.5x10-18 fusions (DD pair)-1 s-1 from neutron detection and 1.5x10-8 fusions (DD pair)-1 s-1 from detection of possible heating; a γ-ray detector showed no evidence of γ rays differing from background
