The surface structure of single crystal metals in reflected in the angular distributions of neutral atoms desorbed during keV Ar ion bombardment. Results are presented here of a study of desorption from a stepped surface, Rh/331/. Recently, classical dynamics simulations of the desorption process were shown to give excellent agreement with ejection data from Rh/111/, and the same model potential has been used to simulate desorption from Rh/331/. The agreement with experiment remains excellent despite the different coordination of the surface atoms on Rh/111/ and Rh/331/. The azimuthal ejection distributions are strongly affected by the steps.
