Abstract
A theory of the angular-resolved photoemission from localized adsorbate orbitals is presented in which the effects of the final state are discussed in detail. This theory is applied to the problem of line shapes and peak positions in a photoemission energy distribution from an orbital localized at the surface. The interference of the wave scattered elastically from the periodic potential of the solid with the wave emitted directly from the adsorbate can cause apparent splitting of a single adsorbate level and 1eV shifts in peak positions.Keywords
