Plasmon mechanism for the energy loss, dissociation, and orientation of fast ions excited by surface-grazing collisions

Abstract

An interaction mechanism is proposed for the inelastic, grazing-incidence scattering of fast ions by metal surfaces which involves coupling of the ion multipoles with surface plasmons. The monopole-plasmon coupling governs the energy-loss spectrum, whereas the higher-multipole interactions raise the ion into electronic excited states. The proposed mechanism is very efficient in dissociating unstable excited molecular ions and in producing atomic excited states with a high degree of orientation. © 1979 The American Physical Society.
