Low-frequency electric microfield distribution in neutral-ion plasmas

Abstract

The knowledge of the electric microfield distribution in multicomponent cold plasma is a necessary condition to solve several problems. In particular, the calculation of the spectral line shapes for an ion, taken as radiator in plasma consisting of neutrals and ions point is one of these problems requiring such distribution. In this work, we are interested in the electric microfield distribution in two-component cold plasma. To reach this goal, we used a useful method based on ”cluster expansion”, widely known in statistical mechanics, in the independent particle approximation. Here we only use the first term of the Baranger-Mozer formalism. The main interactions used are ion-ion and ion-neutral interactions.
