Theory of angle-resolved photoemission from the bulk bands of solids. II. Application to Ag(111)

Abstract
It is shown that the angle-resolved photoemission spectra computed from the theory developed in Paper I, which is based upon a free-electron final state, atomic dipole selection rules, and the band structure of the bulk, are in good agreement with the experimental spectra from a Ag(111) surface for hν=16.9, 21.2, 26.9, and 40.8 eV. There is some sporadic indication that multiple-scattering effects are present in the spectra obtained for hν=40.8 eV. We conclude that there are no significant modifications of the bulk bands at the surface, nor any conclusive signs of surface states.
