Abstract

Calculations of the angular distributions of soattered ions were used to simulate Impaot Collision Ion Soattering Speotrometry (ICISS) experiments. The oalculations were performed first for 2-keV Na+ ions inoident on the Pt (111) surface, a case for whioh Auger neutralization should be negligible. These oalculations were fitted to the experimental data of Niehus and Comsa to provide information about the surfaoe struoture of the sample and the trajeotories of the inoident ions. A first-order deoay model for Auger neutralization was inoluded with the oalculations for Na+ to alloy the simulation of ICISS soans for 2-keV Ne+ ions on the same surfaoe. From these simulations, the Auger neutralization half-life for Ne+ soattered from Pt was found to be 1.30 ± 0.10 femtoseoonds.
