By use of the electron‐phonon matrix elements for Cu derived in a preceding paper (in the form with plane‐wave parts only) the anisotropic functions of the scattering rate and the mass enhancement, as well as the electrical resistivity and the Hall coefficient for several orientations of the magnetic field are calculated as functions of the temperature. The agreement with the experimental data is satisfactory, though the local maximum of the Hall coefficient, characteristic for the scattering anisotropy, appears at lower temperatures than measured. This and other deficiencies, however, may be uniquely related to the simplified form of the matrix elements and should be overcome when the d‐parts of the pseudo wave functions are retained. The present considerations are thought to explain also some discrepancies reported for Al.
