Abstract

Kinetic equations for the process of multiphoton bremsstrahlung of electron in a matter have been used to derive the equations for the moments of distributions of electrons over the number of emitted photons and over the energy loss. The equations for the moments have been solved in continuous slowing down approximation. It has been shown that the moments of multiphoton distributions can be expressed in terms of the moments of macroscopic differential cross section of the process. The results of analytical calculations have been compared with the data of Monte Carlo simulation.
