Abstract
We are carrying out experimental and theoretical studies of optical radiation emitted during grazing incidence collisions of ions with surfaces. This effort is directed at elucidating the mechanisms of formation and destruction of anisotropically populated excited states at surfaces. This has relevance not only to grazing incidence experiments, but also to ion backscattering, sputtering, transmission through foils, and in general the interactions of excited states with surfaces. The experiment is illustrated schematically in Fig. 1. Ions are incident at grazing angles to the surface. After interacting with the surface, neutralized particles proceed through an applied electric field region and then into the observation region where optical radiation emitted perpendicular to the collision plane is detected. The polarization of this radiation can provide information about the nature of the electronic state produced during the encounter with the surface.
