Abstract

Abstract Impact collision ion scattering spectroscopy (ICISS) was employed to analyze a Cu(110) surface utilizing 5 keV 6Li + and 3.5 keV 4He + projectiles. The experimental data revealed large differences between the polar-angle dependence of the scattered yield of Li and He ions, despite the fact that the scattering cross sections for the two projectiles were approximately equal. The differences in the scattering behavior are attributed primarily to the Auger neutralization of backscattered He. A model for quantitatively fitting the neutralization behavior is discussed.
