Abstract
A theory of angle-resolved photoemission from the surface of a random alloy is described. It is argued that this theory contains a proper treatment of the disorder (via the Korringa-Kohn-Rostoker coherent potential approximation, KKR CPA), the surface, the LEED-type final state, and the electron-photon matrix elements. The results are illustrated by comparing calculations for pure Cu and Cu-Ni alloys.Keywords
