Abstract
Oscillations in the low-energy noble-gas ion-scattering cross sections versus primary ion energy have been observed for a number of solid surfaces. This behavior is ascribed to resonant electron exchange between electronic states of the surface atom and the primary ion. The oscillations are sensitive to the particular electronic energy levels and to the chemical environment of the surface atom.Keywords
