In this work, not moving from the diffusion equation for the wave equation for the wave equation in the first approximation takes into account the electron scattering mean free paths and thus improve the approximation of continuous slowing down. This approach allows the construction of a model kinetic equation equally well to take into account both elastic and inelastic interactions in the transport of particles in matter.
