In this chapter the various models and approximations used for describing the static atom-surface potential are reviewed and analyzed. The potentials are of fundamental importance for the calculation of the elastic scattering of atoms from surfaces. These potentials also are the basis for the calculations of the inelastic scattering from surface phonons on insulator surfaces, discussed in detail in Chap. 7. In the case of metal and semiconductor surfaces the semi-empirical parameters used to describe the modifications of the potential resulting from the spill-out of the conduction electrons are discussed. The theory of inelastic surface phonon scattering from metals and semiconductors is the subject of Chap. 8.

Abstract
In this chapter the various models and approximations used for describing the static atom-surface potential are reviewed and analyzed. The potentials are of fundamental importance for the calculation of the elastic scattering of atoms from surfaces. These potentials also are the basis for the calculations of the inelastic scattering from surface phonons on insulator surfaces, discussed in detail in Chap. 7. In the case of metal and semiconductor surfaces the semi-empirical parameters used to describe the modifications of the potential resulting from the spill-out of the conduction electrons are discussed. The theory of inelastic surface phonon scattering from metals and semiconductors is the subject of Chap. 8.
