Abstract : Phonon-induced intraband d to d electron scattering is shown to be primarily responsible for superconductivity in transition metals. This differs from Hopfield's theory, according to which phonon-induced d to d electron scattering is unimportant. A formula is given for the superconducting transition temperature Tc as a function of measurable normal-state quantities and an effective bare electron-ion potential. The formula describes the qualitative variation of Tc among transition metals and yields quantitative values of Tc for alloys, given Tc for the constituent elements. (Author)
