Quantum theory of energy loss by test ions to plasma
Abstract
A fully quantum theoretical calculation is performed for the average energy loss rate by test ions released in a plasma. The calculation derives from the divergence-free kinetic theory of Kihara (1964) and Honda (1964). The rate is expressed in terms of several auxiliary functions which may be evaluated numerically for a given test ion once the Maxwellian temperatures and densities of each plasma species (electrons and ions) are specified. The examples considered earlier by Sigmar and Joyce (1971) are reevaluated and the accuracies of their approximate calculations are found to be on the whole quite good. A number of new quantitative results are presented.
