Abstract : Phononinduced 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 phononinduced d to d electron scattering is unimportant. A formula is given for the superconducting transition temperature Tc as a function of measurable normalstate quantities and an effective bare electronion 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)
