The influence of lattice strain on the residual resistivity of dilute alkali alloys

The effect of lattice distortion on the residual resistivity of dilute alkali alloys has been calculated using the lattice statics method due to Kanaki and the empty core Ashcroft model pseudopotential. The dielectric function due to Singwi et al was used for calculating the ion-ion and ion-electron interaction potentials. The correction for lattice distortion was found to be 5-30%, which confirms the estimate given by Ziman. The overall agreement with experiment is of the same order as the phase shift calculation without lattice distortion.
