Light Emission and Circular Polarization by Ion Surface Scattering at Grazing Incidence
Studies of optical radiation from particles reflected from surfaces provide important information on particle-surface electronic processes. Of particular interest have been measurements of radiation arising from grazing incidence collisions of ions with single crystalline surfaces [1–4]. Here we report on the influence of the oxygen coverage and the crystallographic orientation on the intensity and circular polarization of the light which is emitted from 200 keV He projectiles after scattering at a (110) surface of a (60/40)NiFe single crystal at grazing incidence.
