Abstract
Results of a study of inelastic scattering in Ne+ collisions with a po lycrystalline Mg target, performed by measurements of charge fractions , are reported. In agreement with previous studies, ion production is found to be due to binary collisions with surface atoms and the charge fractions can be well described by a simple exponential dependence on the perpendicular velocity in the outgoing trajectory. This is also s hown to be the case for Ar+ collisions. Charge fractions and angular d istributions of scattered particles are strongly affected by surface r oughness effects.
