Excited States Lifetimes Near Surfaces
Results from calculations of energy shifts and broadening of neutral and negative ion states near clean and impurity covered metal surfaces are presented. The results of these calculations shows that, in general, several different atomic states can be populated close to the surface. It is shown that for the proper description of charge transfer in such situations, it is crucial to include the effects of intra-atomic electron correlation.
