Molecular-dynamics investigation of deuteron separation in PdD1.1

A molecular-dynamics simulation was done to investigate the D-D distances in above-stoichiometric ${\mathrm{PdD}}_{1.1}$. Different potentials were used in an attempt to optimize the chances of close D-D approach. At the two temperatures studied, 300 and 1300 K, no distances closer than 0.7 Å were found, thus giving no evidence for the short distances needed to produce fusion in the material.
