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.
