Estimate of nuclear fusion rates arising from a molecular-dynamics model of PdDx

We describe an estimate of the fusion rate of deuterium in palladium metal based on molecular-dynamics simulation. Quantum effects on the motion of the deuterium are treated semiclassically and the effects of electronic screening of the interactions are studied by varying a screening parameter in the potentials. We find very low fusion rates of the order of 10-150 s-1 per deuteron, consistent with bounds suggested by Leggett and Baym.
