Abstract

Using self-consistent density functional formalism we show that the electronic structure of PdH(D) is influenced by the zero-point vibration of hydrogen and deuterium. This quantum effect makes a small but significant contribution to the superconducting transition temperature Tc of PdH(D). The reverse isotope effect on Tc is found to be dominated by the changes in the force constants between PdH and PdD.
