Resumo

The results of solving the problem of describing the dependence of the charge state of the ion beam on their velocity for all atoms of the periodic system of elements are presented. The values of the basic parameters that are necessary for calculating the charge state of the ion beam are determined and tested by comparing the calculations of the stopping power with an array of experimentally measured values.
