On the Vibrations of the Electronic Plasma

Abstract

The vibrations of the electronic plasma are considered, which arose as a result of an arbitrary initial non-equilibrium distribution in it. It is shown that the vibrations of the field in plasma are always damped, and the dependence of the frequency and of the damping decrement on the wave vector is determined for asmall and for large values of the latter. The penetration of a periodical external electric field into the plasma is considered. The case of the frequency of the external field being almost at resonance with the proper frequency of plasma is considered spearately.
