Observations were made of the anomalous production of ⁴He 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 D₂O. A mass analysis of the remnant Pd powders after the 2000-hr heat production revealed substantial production of ⁴He atoms.
