The dynamics and kinetics of the translational relaxation, adsorption, and desorption during the interaction of gas atoms with a metal surface
Abstract
The dynamics and kinetics of translational energy accommodation accompanied by the adsorption and desorption of gas particles are investigated analytically using the 'potential box' approximation. It is shown that the energy and spatial distributions of desorbed particles are largely determined by the dynamics of their interaction with a metal surface, which is explained by the fact that desorption, like adsorption, is an essentially nonequilibrium process. The calculated accommodation coefficients are compared with experimental data on the accommodation of the translational energy of inert gas atoms on the surface of tungsten.
