Charge exchange and energy dissipation of particles interacting with metal surfaces

Abstract

Theoretical and experimental results for the charge state and energy loss of low-energy He scattered off a Ni(110) surface are compared. A first-principles theory is used to analyze both the charge state and the energy loss. Charge-exchange processes are of primordial importance to explain the energy-loss spectra. Energy straggling plays an important role in the system under study.
