Abstract

The local spin-density functional method with an optimized effective potential and a self-interaction correction is used to study the energy structure of hollow atoms or ions in the bulk of metallic materials as well as in the vacuum. Based on the method, we have studied the emitted x-ray spectra and Auger spectra of the Nq+ hollow atoms and ions in the bulk of Al as well as in the vacuum. The experimental Auger spectra in the collision of N6+ with an insulating surface and conducting surface can be well understood based our studies. Meanwhile, the stopping power of a highly charged ion near the surface is also studied by the linear density response theory.
