Abstract Maps of the scattering rate anisotropy for Cu(H) have been obtained using two different representations, one based upon ß phase shift analysis, and the other using a symmetrized Fourier series. The partial wave analysis indicates that p wave scattering is heavily dominant, although the analysis does not account entirely for the large scattering rates observed on the Neck and Dogsbone orbits. The dominance of p wave scattering suggests that the screening of the interstitial proton is carried out primarily by electrons in conduction states derived from orbitals with p‐like symmetry.
