Abstract
Fast He+-, Li+-, and Na+-ions with energies ranging from about 5 keV t o 360 keV are scattered under a grazing angle of incidence from a magn etized Fe(110) surface. The spin polarization of electrons captured in to excited atomic terms is investigated via the polarization of the fl uorescence light. We present data for this capture as a function of pr ojectile velocity and of target temperature. For the Fe(110) surface w e observe a pronounced dependence of the spin polarization on the proj ectile velocity and discuss our results in the framework of some simpl e theoretical concepts.
