Abstract

A simple version of the theory of superconductivity is presented. The final result for Tc is very similar to McMillan’s formula, which expresses Tc in terms of electronic quantities and the distribution of the eigenmodes of the lattice vibrations. Taking this distribution from neutron scattering experiments and the electronic properties from first principle band structure calculations, Tc values for Palladium based hydrides and deuterides are obtained in good agreement with the experimental data.
