We evaluate the potential energy of a He atom near an ionic surface by summing a two-body potential as derived from molecular physics. Corrugation parameters and binding energy are derived for a set of four alkali halide surfaces and compared to recent atom scattering data. Finally we comment on the possibility of performing a surface crystallography of ionic crystals by means of atom scattering. © 1985 American Institute of Physics.

Abstract
We evaluate the potential energy of a He atom near an ionic surface by summing a two-body potential as derived from molecular physics. Corrugation parameters and binding energy are derived for a set of four alkali halide surfaces and compared to recent atom scattering data. Finally we comment on the possibility of performing a surface crystallography of ionic crystals by means of atom scattering. © 1985 American Institute of Physics.
