Abstract
First principles calculations of the shifts and lifetimes of atomic energy levels outside clean and impurity covered surfaces are presented. It is shown that in the presence of coadsorbed impurities both the widths and the shift of atomic levels with position can be strongly modified compared to the clean metal case. Such changes can significantly alter the probability for charge transfer between an atom and a surface. This effect is illustrated by an application to a series of recent ESD experiments of excited H from K covered Pt(100).
