Evidence for the anisotropic limit for electron-electron scattering in potassium

Abstract
The recent data for the temperature dependence of the electrical resistivity of a highly strained sample of potassium are analysed to obtain the electron-electron scattering contribution to the resistivity. The resulting value provides evidence for the existence of the 'anisotropic limit' for electron-electron scattering proposed in the recent theory of Kaveh and Wiser (1980).
