Multi-term Approach to Angle Dependence in the Boltzmann Distribution Function
Author:
Abstract: In overwhelming majority of works on plasma physics the electron distribution function is used in so named two-term Lorentz approximation for velocity directions. It is caused by large dimension of phase space, in which a distribution function is to be appeared, and a search for simplification. In many of situations the function is almost isotropic indeed. But there exist also situations, where this approximation is not sufficient. Simplest of them – an absorbing wall – is considered here.
