Abstract
The electron-phonon contribution to the resistivity of a dilute metal alloy at low temperatures is drastically different from that of the ideally pure host metal if the conduction-electron cross section for impurity scattering varies with energy on a scale comparable with or less than the Debye energy of the host metal. Experimentally the effect should be of particular importance for magnetic or nearly magnetic transitional impurities in appropriate nontransitional hosts.
