Abstract

We report here studies of the angular distribution of photo-emitted electrons from the (100), (110) and (111) surfaces of a number of CuxNi1-x random alloys, using ArI, NeI and HeI incident radiation, and compare the results with calculations based on the coherent potential approximation for non-overlapping muffin-tin potentials (KKR-CPA). Good overall agreement confirms the existence of k-dependent energy bands in random alloys and demonstrates that U V angle-resolved photoelectron spectroscopy (ARPS) is a useful tool for studying the detailed behaviour.
