Dynamic Interaction of Nitrogen Atoms with the Surface of an Aluminum Crystal

A possibility of reconstructing the ion-atom dynamic interaction potential from the dependence of the rainbow scattering angle of nitrogen atoms under the conditions of grazing incidence on the surface of an aluminum crystal on the total kinetic energy of the accelerated atomic particles is demonstrated. The parameters of the dynamic interaction potential are determined within the energy range from 10 to 70 keV using the best possible fit between the calculated dependence of the rainbow scattering angle on the energy of the particles incident on the aluminum crystal surface along the crystallographic directions and the available experimental data.
