Calculation of charge-exchange in lithium ions/atoms scattered from cesiated metal surfaces

Abstract

The charge states of Li ions/atoms scattered from a Cs/W(110) surface have been calculated as a function of work function and the temperature of surface in terms of the time-dependent Newns-Anderson quantum model with the intra-atomic Coulomb interaction. The calculated results are in good agreement with the experimental data. Furthermore, the probabilities of charge states of the moving Li ions/atoms approaching to and leaving from the surface are demonstrated.
