Roles of lateral interactions between adatoms and local surface geometry in determining the binding energies of core electrons in adsorbed species

Abstract

The MSXα cluster technique is used to calculate the energies of core and valence levels in models for oxygen chemisorbed on lithium. It is shown that it is possible to maintain traditional concepts of the chemisorbed state if the clusters are considered to be open electron systems taking due account of lateral interactions in the surface and bulk regions.
