Abstract
Analytical formulas have been obtained for the energy spectrum F +(E) of atomic ions and the energy dependence of the degree of ionization α+(E) of atoms sputtered from metals in the nonlinear collision cascade mode. The comparison of the dependences α+(E) for the linear and nonlinear sputtering modes indicates a significant difference between the mechanisms responsible for the formation of the charge composition of atomic ions.
