Abstract
The role of Coulomb correlations on the resonant charge transfer in atom scattering on an atom adsorbed on a metal surface has been studied theoretically within the Hartree–Fock approximation and the time-dependent Anderson–Newns model. Using the evolution operator technique the probabilities of the different charge states of the back-scattered atoms were calculated for broad range of parameters. In particular, the effect of the constant or z-dependent ( z being the distance of the moving atom from the surface) effective intra-atomic Coulomb correlations was analysed.
