The results (B7)-(B9) were used to obtain the expressions (34)-(39). (For simplicity we omitted the symbol " on the F's.) Notice that the terms proportional to cob represent the effects of the deviation from Maxwellian plasmas (c06 is given by (12)). This research was supported by a grant from the US—Israel Binational Science Foundation, Jerusalem, Israel.

N2 - Generalized expressions for the rates of change of the momentum, energy and thermal anisotropy of fast, charged particle beams interacting with non-Maxwellian multi-species plasmas are derived. The results hold for the case of spherically symmetric systems and, therefore, are relevant for inertial confinement fusion schemes driven by fast charged particle beams and for various astrophysical situations. The calculations are based on the Fokker-Planckformalism. The effects connected with the departures from the Maxwellian distribution functions are expressed in terms of their fifth moments, Ci = £(vr - (vr))4f1dv which reflect the role of the non-Maxwellian tails. The familiar stopping power expression holding for Maxwellian targets is recovered as a particular case.
