Abstract

A simple model is proposed by means of which nearest neighbor displacements round a vacancy and an impurity in a metal may be taken into account in calculating excess resistivities. Using Tewordt's calculated nearest neighbor displacement for a vacancy in copper we obtain from our model an excess resistivity of 0.94 μohm cm per atomic percent. The same model without strain yields 0.97 μohm cm. The case of silver impurities in copper is also considered and it is shown that a radial increase of ∼3% in the nearest neighbor distance is sufficient to account entirely for the observed excess resistivity.
