Popis:	The energy bands of an atom adsorbed on a crystalline surface have been calculated for representative hypothetical systems. The corrugation corresponding to the atom-surface interaction potential of several of the studied systems is similar to the corrugation reported for systems in which the surface holds a layer of adsorbed particles. Characteristic features of the band structure, that depend on the corrugation of the atom-surface interaction potential and on the depth of the associated bound-state, have been found. The bands of all the systems evolve to parabolic shaped bands displaced downwards with respect to the corresponding freeatom parabolic bands. Theoretical studies of atom-surface elastic scattering revealed that bound-state resonances do not appear if the energy of the incident atoms is not high enough to reach the region where the band is parabolic.
