摘要
Recent experiments by Rau and his colleagues [Phys. Rev. Lett. 64 (1990) 1441; DIET V (Springer, New York, 1992); Ionization of Solids by Heavy Particles (Plenum, New York, 1992)] explore the energy spectrum of electrons emitted from metal surfaces, in response to the reflection of positive ions reflected from the surface, at grazing incidence. We develop a theory of the emission process wherein the Coulomb field of the ion excites particle-hole pairs in the substrate, taken here to be jellium. We obtain a general expression for the energy and angle variation of the emitted electrons, for an ion trajectory which may penetrate into the substrate before reflecting off the planes of substrate nuclei. The result is expressed as an integral over the density-density response functions chi(zz'; Q(parallel-to)omega the substrate. Special limits are explored, with emphasis on glancing incidence. We do not consider Auger processes, in which the ion is neutralized through acquisition of a substrate electron.
