Herein is described a calculation of the effective coffision frequency νeffof a low- density, shock-heated argon plasma under the influence of a weak electric field which oscillates harmonically with angular frequency ω. It is shown that, for the high frequency case ω >whereis the collision frequency in a Maxwellian gas plasma, one has νeff⋍ 2, provided that the imaginary part of the argon plasma conductivity is negligibly small in comparison to the real part. The influence of the theoretical model used to calculate νeffon the values of the electron temperatureTederived from measurements is compared with the results obtained in a data reduction for which the hard-sphere model for particle encounters was utilized.

Weakly Ionized Plasma

The results of two experiments in a weakly ionized turbulent argon plasma are compared with a theory for the spacewisespectrum of the electron – ion density fluctuations of the plasma. It would appear that the theoretical predictions are in reasonable agreement with the results of these experiments. The theory, based on a quasi-static formulation of the Boltzmann equations, is a direct consequence of the Boltzman equations for the electrons, ions and neutrals in theweakly ionized plasma. A Heisenberg model is used for the turbulent diffusion coefficient of the plasma.
