摘要：

Energy losses of MeV H and He ions after interaction of clean surfaces of several NaCl-type crystals at glancing-angle of incidence are investigated. From the most probable energy losses of ions reflected from the surface atomic plane, position-dependent stopping powers of the (100) surfaces of NaCl, KCl, KBr, SnTe, PbSe and PbTe for MeV H and He ions are determined. The results are explained by a sum of the stopping caused by dynamic response of valence electrons to fast ions in vacuum and that due to single ion-electron collisions.
