Energy losses of a charged particle in a plasma in an external field allowing for the field action on plasma and particle motion

In this paper we present polarization losses of a charged particle in a Maxwell plasma placed in an external HF electric field allowing for oscillations under the action of an external field of both the particle and plasma electrons. Deriving the expressions for particle losses, we assumed that the vector of translational motion of the particleu is directed at an arbitrary angle with respect to the external HF field vector.[PUBLICATION ABSTRACT]
