Abstract

We present electron momentum spectroscopy measurements of the electronic structure of copper single crystals. Generally, good agreement was found with the band dispersion as measured by photoemission. The energy-resolved momentum densities are quite anisotropic. Observed diffraction effects can be disentangled in first order, and the experiment compares well to calculated momentum density. Deviations of the Fermi surface from spherical symmetry are resolved by this scattering experiment. Many-body effects cause lifetime broadening of the quasiparticle peak and a smooth tail extending to higher binding energies, but no clear satellite structures were found.
