The impact of electron–electron collisions on the spatial relaxation of electrons in the column-anode plasma of a glow discharge, acted upon by a space-independent electric field and initiated by a constant influx at the cathode side of the plasma, is investigated in inert gas plasmas. The ...
In strongly coupled, degenerate plasmas, the electron collision frequency has been described by the Ziman formula with the ion-ion correlations modeled by the classical one-component plasma (OCP). However, this model fails to reproduce the correct quantum Lenard-Balescu result in the weak-coupling...
The theory of erenkov radiation from magnetoplasma has been modified to account for the effect of electron collision frequency. The results are compared with the erenkov theory for collisionless magnetoplasma. The erenkov radiation in the magnetosphere is unaffected by electron collisions. In the ...
For a specific electronic transition induced by electron collision, the excitation rate depends on the energy distribution of electrons with kinetic energy exceeding the excitation threshold, as well as an energy-dependent probability expressed as a collision cross section. Inelastic collisions involving ...
This mode is excited by ion oscillations originating in the wings of the distribution where the plasma becomes non-neutral. The ion temperature shows evidence of an enhanced electron-ion collision rate in the presence of the magnetic field. Ultracold neutral plasmas provide a rich system for ...
The kinetic theory of the electrons in a strongly ionized, collision dominated plasma is reconsidered. By means of a perturbation expansion combined with a multiple time scales formalism, the kinetic equation for the electron distribution function is solved. The usual integro- differential operator is...

DAMPING OF ELECTROMAGNETIC WAVES IN LOW-COLLISION ELECTRON-ION PLASMA.Using previously developed methods of two-dimensional Laplace transform, we obtain the characteristic equations k(蠅) for electromagnetic waves in low-collision fully ionized plasma in a plane geometry. We apply here a new technique...
