Abstract

Overlayers of C, N, and O on Mo(001) have been studied by 500-eV K+ -ion scattering. The energy distributions and their dependence upon incident angle are found to depend strongly upon coverage and annealing temperature. Enhanced specular scattering is extremely sensitive to changes in adsorbate ordering observed by low-energy electron diffraction. The enhancement is explained by a novel scattering mechanism discovered by computer simulation.
