Аннотация
The spatial distributions of ions (K + , Na + ) passed through thin polycrystalline and single-crystalline Al films with the thickness from 180 to 600 Angstrem and critical channeling angles have been studied. The ion energies have been varied within the range E 0 =10-30 keV. It has been shown that an increase in the energy of the primary ion beam leads to a decrease in the width of the maxima of the angular distribution, which is associated with a decrease in the critical channeling angle psi cr . It has been found that the value psi cr does not exceed 4-50 for axial channeling and 9-100 for planar channeling Keywords: critical angle, passage of ions, angular distribution, channeling, spatial distribution.
