Ionization Probabilities of Desorbed Atoms

Abstract

Ionization and neutralization probabilities of atoms desorbed from metal surfaces are calculated with the use of the Newns-Anderson model. The main purpose of this calculation is to examine the effect of the intraatomic Coulomb interaction on such probabilities. For the case where the desorption velocity v is infinite, the effect of the Coulomb interaction is treated exactly. For other cases of finite v, the retardation effect on the quantity is taken into account phenomenologically on the basis of a static solution of the model.KeywordsCoulomb InteractionSymmetric CaseIonization ProbabilityRetardation EffectNeutralization ProbabilityThese keywords were added by machine and not by the authors.
