Observation of Anomalous Heat Release and Helium-4 Production from Highly Deuterated Palladium Fine Particles

Abstract

Observations were made of the anomalous production of 4 He atoms as well as the anomalous heat release when Pd fine particles are highly deuterated inside an enclosed Pd metal vessel used as a cathode in electrolysis of D 2 O. A mass analysis of the remnant Pd powders after the 2000-hr heat production revealed substantial production of 4 He atoms.
