Abstract
We present the results of an experimental study of Ar +, N + and N + 2 ions scattering from a NaCl(100) surface. We aim to clear up their role and find out the singularities of resonant charge exchange for different cases: the basic ion energy level lies (1) inside the valence band, (2) on the bottom of the valence band, (3) in the forbidden band. The theoretical calculations are carried out in terms of the method given in Tully [Phys Rev, 16, 4324 (1977)] and Bloss and Hone [Surface Sci, 72, 277 (1978)], and consider the real electron structure of the NaCl surface. Good agreement between theoretical analysis and experimental data is obtained. On this basis an explanation for detect formation regularities and stimulated condensation as a function of ion energy is given.
