Momentum Nonconservation and the Low-Temperature Resistivity of Alloys

Abstract
The temperature-dependent part of the electrical resistivity of a dilute alloy at low temperatures is generally much larger than that of the pure host metal. A simple calculation based on the relaxation of the usual conservation requirements for electron-phonon scattering in the alloy leads to a formula which contains no free parameters and which agrees well with experiment for a wide variety of alloy systems.
