Abstract
Various light ions were scattered at grazing incidence from a highly polished Al2O3 single crystal and from a thin film of Al2O3 on graphite. The energy of incident particles was varied from 390Â eV to 1200Â eV. For scattered positive oxygen and carbon ions, negative ion fractions of up to 14% and 3%, respectively, were recorded. For scattered positive hydrogen ions, the negative ion fractions reached the percent level.
