Title: Angle Resolved Auger Surface Spectroscopy
Published: November 01, 1976
Abstract: The angular distribution of electrons ejected in core-valence-valence Auger transitions of atoms chemisorbed on metal surfaces is considered theoretically. Since the valence electrons participating in the Auger transition are also involved in chemical bonding to the surface, these initial states contain information pertaining to the chemisorption bonding geometry. The role of the initial state symmetry in determining the angle resolved Auger surface spectrum (ARASS) is investigated through model calculations and is found to be small. Thus the ARASS is expected to be a smoothly varying function of angle with {plus or minus} 15% modulations due to diffraction effects, in agreement with recent experimental results for S adsorbed on Ni(100).
