摘要：
Calculations are carried out for the energy accommodation coefficient at a gas-surface interface using a recently developed classical mechanical theory of atom-surface collisions that includes both direct scattering and trapping-desorption processes in the physisorption well of the interaction potential. Full three-dimensional calculations are compared with the available data for the accommodation of rare gases at a tungsten surface and reasonable agreement is found for the heavier gases for which classical physics is expected to be valid at all measured temperatures.
