Abstract : The report reviews experimental studies of gas-surface scattering reported in the period from approximately 1969 through the first half of 1972. It emphasizes rare gas scattering from a variety of metal single crystals at incident energies from about 0.025 eV to nearly 20 eV, and includes a discussion of the various scattering regimes in that energy range. In addition, light gas scattering from LiF and certain highly structured metal surfaces is surveyed. The observation of single-phonon inelastic events are described. Recent studies of desorption phenomena are reviewed. A correlation of the various results is made and areas in which questions remain are indicated. Apart from parametric correlations, no attempt is made to assess the validity of the various theoretical models that have been developed to describe the scattering process. (Author)
