Evaluation of the distribution functions of spatial derivatives of an ionic electric microfield in plasmas by using only the central interactions approach

Abstract

By using some physical approximations, distribution functions of spatial derivatives of components of an electric ionic microfield in plasmas have been theoretically evaluated. The particles are considered quasistatic. Only interactions between charged emitter and perturber ions are taken into account. Our theoretical results have been compared with those found in the literature. The few differences found are discussed. Some properties of distribution functions of spatial derivatives have been deduced from curves.
