The results of applying the statistics of a discrete multiple scattering process to analytically describe the dependence of the charge state of light ions in matter on particle velocity are presented. It is shown that the use of a technique based on taking into account the dependence of the charge state of the beam ions on the ratio of the ion velocity to the minimum velocity of the electrons of the substance makes it possible to calculate the stopping power of the substance for lithium, beryllium, boron and carbon ions of medium and low energies, corresponding to the experimental results.
