Stopping Power of Matter for a Beam of Monoenergetic Alpha Particles

The results of using the statistics of multiple scattering to describe the dependence of the stopping power S of matter on the energy E-0 of a beam of alpha particles are presented. It is shown that the application of a new technique based on taking into account the dependence of the charge state of beam ions on the ratio of the ion velocity to the minimum velocity of substance electrons makes it possible to carry out calculations S appropriate for experimental results in a wide range of particle energies E-0.
