Abstract

The azimuthal dependence of the energy distribution of Li+, specularly scattered from Mo(001), has been obtained for several incident energies Ei. The energy distributions exhibit one or two peaks, which always lie below the kinematical single scattering energy and which have intensity and energy that depend upon the azimuth. Due to trajectory focusing, the intensity is strongly peaked along the [100] azimuth for Ei ≲ 500 eV, but at higher Ei the intensity enhancement is shifted toward the [310] azimuth. Results of computer simulation give reasonable agreement with experimental observations. Analysis of the simulated trajectories allows identification of the scattering mechanisms which contribute to each portion of the spectrum.
