Popis:	He + -ions with energies from 3 keV to 1.4 MeV are scattered from a clean and flat Al (1 1 1)-surface under a grazing angle of incidence, and the scattered projectiles are analyzed with respect to charge states. We observe defined kinematic thresholds for the formation of He + – as well as of He 2+ – ions which are in agreement with the onset of a kinematically induced Auger-ionization process. Comparison of our data with foil transmission experiments shows a clearly different dependence of the charge state fractions on the projectile energy (velocity).
