Abstract
A simple theory of lifetime broadening due to scattering from isolated impurities in noble-metal hosts is presented and used to calculate the Dingle temperature observed in de Haas-van Alphen experiments. Details of the scattering anisotropy are easily calculated when the impurity is a transition metal. Numerical estimates of the Dingle temperatures for three extremal orbits are in good agreement with experiments on CuNi and CuZn.Keywords
