Beam-Druyvesteyn plasma interaction

The interaction of an electron beam with a Druyvesteyn plasma is considered. The kinetic equation for the distribution function for the electrons in interaction with the plasma is written in the first part of the paper. The equations for momentum and average kinetic energy for the beam's particles and also for some characteristics times are obtained. The numerical calculation of the dynamical friction coefficient and the diffusion tensor components in the velocity space was obtained. (Auth.)
