	abstract = {Nonequilibrium distributions of space plasmas are often characterized by extended high-energy tails. This paper provides a detailed analysis of the relaxation of such isotropic nonequilibrium plasmas. We consider an energetic charged species dilutely dispersed in a fully ionized plasma, which acts as a heat bath at equilibrium. The minor constituent is referred to as a "test particle" and collisions between test particles are not included. We study the approach to equilibrium with a finite difference method of solution of the Fokker-Planck equation appropriate for collisions between charged particles. The solution of the Fokker-Planck equation is also presented formally as an expansion in the eigenfunctions of the Fokker-Planck operator. The main objective of the paper is the calculation of the energy-dependent relaxation times of the distribution function. A strong energy dependence for these relaxation times is anticipated since, for Coulomb collisions, the Rutherford cross-section varies with relative speed g as g(-4). Analogous results for neutral species are presented for comparison in the following paper. (C) 2004 Elsevier Ltd. All rights reserved.},

	abstract = {The transport properties of an ensemble of charged test particles diffusing from infinity through a second charged species that fills the positive half-space are studied. It is assumed that there are no incoming particles at the boundary between the medium in the positive half-space and the vacuum that fills the negative half-space. This problem has been referred to as the Milne problem and has previously been considered for neutral species [M. J. Lindenfold and B. Shizgal, Phys. Rev. A 27, 1657 (1983)]. The present paper examines the rarefied-gas dynamical effects for the Coulomb interaction between the two species. The distribution function of the background gas is taken to be a Maxwellian and the test-particle distribution is determined from a solution of the Boltzmann equation with its expansion in Burnett functions, products of Laguerre polynomials, and spherical harmonics. The extrapolation length is calculated together with the density and temperature profiles and compared with the Chapman-Enskog results valid far from the boundary. A comparison with the previous results for the hard-sphere cross section describing collisions between two neutral species is also presented.},
