Scattering of Positive Muons by Atoms of Inert Gases

In the present work, the cross sections of elastic and inelastic scattering of positive muons by He and Ar atoms at low and medium kinetic energies are calculated by the methods of many-body theory with the use of the ATOM-M software package. For comparison, the results of elastic and inelastic positron scattering at the same energies are also given. The dependence of the phases and scattering cross sections on the charge of the particle and its mass, as well as on the charge of the nucleus of the scattering atom, is discussed.
