Energy- and angle-resolved detection of neutral atoms desorbed from ion bombarded single crystals. Rh{111} and p(2 × 2)O/Rh{111}

Abstract

Measurements of energy- and angle-resolved distributions of neutral atoms desorbed from ion-bombarded single crystals are obtained using a novel multiphoton resonance ionization scheme. Experimental results are compared successfully to molecular dynamics calculations of the ion/solid collision event. This comparison suggests that the distributions from Rh{111} are sensitive to the crystal structure of the top atomic layer. Calculated distributions match experimental ones when oxygen atoms are assumed to adsorb in 3-fold hollow (c-site) bonding configurations.
