Distribution Function of Spatial Derivative of the Ion Electric Microfield Using the Independent Particles Model in Plasmas

In this work the distribution function of spatial derivative of parallel component of quasistatic ion electric microfield in plasma is calculated. Some physical approximations are used in these calculations, where only interactions between charged emitter and perturber ions are taken into account, as first step. This approximation is known as the independent particles model. Some special functions and series are used in these calculations. It is deduced that the distribution function of spatial derivative of the ion microfield may be depend more on the probability of finding the microfield rather than the microfield value itself (© 2012 WILEY‐VCH Verlag GmbH & Co.
