Abstract:

The principal mechanisms of energy and momentum transfer between gas atoms and solid surfaces are considered for the range of impact energies encountered in high-speed flight e.g., up to 10 ev. Included within are 1 introductory discussions of the nature of surfaces, intermolecular potentials, adsorption, and basic gas -surface interaction processes, 2 a critical survey of the definitions of energy and momentum accommodation coefficients, 3 summaries of existing theoretical and experimental results pertaining to the energy accommodation and directional distribution of atoms scattered from a surface, 4 an attempt to formulate the main parameters and regimes of gas- surface interactions, and 5 suggestions concerning future investigations.
