Electron Interactions in Gaseous Discharge Plasmas and their Effect on Cyclotron Resonance

摘要

Electron-electron interactions in gaseous discharge plasmas are tudied. They are found to have an effect on the electrical conductivity of the plasma when it is under cyclotron resonance conditions.nThe magnetic properties of the plasma at cyclotron resonance are first investigated. t is found that, although the resonance conditions take the electron system out of its equilibrium state, the magnetic moment that results in the plasma is of negligible magnitude. Thus, the shape of the resonance is practically unaffected by the magnetic susceptibility of the resonating plasma.nThe effect of the electron-electron interactions on the velocity distribution function of the electrons is studied by taking into account in the Boltzmann equation both the long and the short-range parts of the Coulomb forces.
