Abstract
Energy and angular distributions of Rh atoms ejected from a Rh{111} surface due to keV ion bombardment are predicted from classical dynamics calculations and are compared to those measured using a multiphoton resonance ionization scheme. The comparison is generally quite favorable. For example, the calculated distributions reproduce the changes in azimuthal anisotropy which occur over an ejected-particle kinetic energy range of 5–50 eV. The new detailed experimental data do, however, expose deficiencies in the pair potential, which we believe can be overcome with a many-body potential.
