Neutralization Rates for Low-Energy Ions Scattered From Solid Surfaces
Keyword(s):
AbstractCalculations of the angular distributions of scattered ions were used to simulate impact collision ion scattering spectrometry (ICISS) experiments. The calculations were performed first for 2–keV Na+ ions incident on the Pt(111) surface in the <112> azimuth. The fitting of these calculations to the experimental data provided information about the surface structure of the sample and the trajectories of the incident ions. The inclusion of a first-order decay model for Auger neutralization with the calculations for Na+ allowed the simulation of 2-keV Ne+ ions in the ICISS mode on the same Pt surface. From these simulations it was possible to extract the Auger neutralization halflife for Ne+, found to be 1.30 ± 0.10 femtoseconds.
