A quantum-mechanical model for dissociative sticking, and scattering of a diatomic molecule witbout energy loss at a solid surface is solved exactly. The potential energy surface consists of two channels coupled by a 'late' separable potential. The dependence of the sticking coefficient so on the in

✦ Synopsis
A previously proposed electrostatic model for physisorption at ionic solids is extended to multiple adsorption of small molecules. A new algorithm is developed to avoid interpenetration of the interacting systems. The geometry optimization procedure is described. Ab initio calculations are used for the application of the method Ž . to the adsorption of CO and CO at NaCl 100 surfaces simulated by Na Cl clusters. 2 2 5 2 5
The orientation of the adsorbate molecules in dependence on the cumulative atomic Ž . multipole moments CAMMs of the cluster atoms is discussed.

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 excit

A method for calculating the dependence of equivalent layer thickness on bulk phase composition in athermal binary mixtures has been devised. The prerequisite to the procedure is knowledge of the adsorption excess isotherm and of the cross-sectional area of one component. After integration of the ex
