A theory for light-atom scattering by low-coverage adsorbates on metal surfaces is presented. A model including attractive adatom potentials successfully explains data for CO and Xe adsorption. The radius of the repulsive potential for CO is found to increase by 10--20% upon adsorption. It is shown theoretically that random adsorption and island formation can be distinguished, all data for CO being consistent with the former. Xe data show both mechanisms, depending on coverage.
