Abstract
The impurity resistivity is calculated for various solutes dissolved in copper using a 'dilute' Korringa-Kohn-Rostoker description of the host and impurity phase shifts deduced from experiment. It is shown how a concise solution of the Boltzmann equation can be obtained by exploiting the cubic symmetry. The transport relaxation time is calculated and compared with the total scattering time and with various other approximate relaxation times. It is found that the spherical-band approximation is frequently quite inaccurate while the Ziman approximation reproduces the resistivity accurately but exaggerates the anisotropy of the relaxation time.
