摘要

在电子分布函数在某方向上不对称的情况下，推导了电子与重中性粒子弹性碰撞积分的完全微分展开。这个推导是在假定电子的动能大大超过原子和分子的热运动能的情况下进行的。它显示了如何利用结果展开来推导电子分布函数矩的方程。

Complete Differential Expansion of the Integral of Elastic Collisions of Electrons with Heavy Neutral Particles

The derivation of the complete differential expansion of the integral of elastic collisions of electrons with heavy neutral particles is performed for the case when the electron distribution function is not symmetric with respect to some direction. The derivation is made under the assumption that the kinetic energy of electrons greatly exceeds the energy of thermal motion of atoms and molecules. It is shown how the resulting expansion can be used to derive equations for the moments of the electron distribution function.

期刊介绍： Plasma Physics Reports is a peer reviewed journal devoted to plasma physics. The journal covers the following topics: high-temperature plasma physics related to the problem of controlled nuclear fusion based on magnetic and inertial confinement; physics of cosmic plasma, including magnetosphere plasma, sun and stellar plasma, etc.; gas discharge plasma and plasma generated by laser and particle beams. The journal also publishes papers on such related topics as plasma electronics, generation of radiation in plasma, and plasma diagnostics. As well as other original communications, the journal publishes topical reviews and conference proceedings.
