✦ Synopsis

A simple quantum-mechanical model for the sticking, and inelastic scattering of an atom at the surface of a cold solid, with energy loss to either an electron or a phonon system, is solved exactly. The elastic gas-solid potential is a 6 function in front of a hard wall, and the coupling to the excitation system of the solid occurs at the 6 function. The behaviour of the sticking coefficient as the energy E of the incoming atom goes to zero is s=,!Y2, and the strong-coupling limit is also s-to. The full dependence of s on E is exhibited for one parameterization oithe model.

A nonlinear truncated model, concerning thermodiffusive chaos in gaseous media, has been employed to represent evaporation of a solid body on the basis of nonlinearity at the solid/gas interface. Solid/gas consumption has been described in the cell which is characterized by the wavenumber of the int
