Interaction of Impurity Ions with a Weakly Non-Maxwellian Simple Hydrogenic Plasma.

摘要

The average acceleration of an ensemble of ''test particles'' in a plasma is called the ''dynamical friction''; the average rate at which their velocity vectors spread out in velocity space is expressed in a velocity-space diffusion-rate tensor. These quantities are derived for impurity ions interacting with a weakly non-Maxwellian simple hydrogenic plasma. The distribution functions for the plasma ions and electrons are written explicitly. 5 refs., 3 figs. (ERA citation 13:055860)
