The electron-electron collision term of the steady-state Boltzmann equation is replaced by a simple relaxation term that effectively linearizes the equation. Additional assumptions are made to simplify the equation further. Ionization is ignored and a two-level atom is assumed. The effects of a DC electric field are included. Using the relaxation term to account for electron-electron collisions, an approximate analytic solution is derived. Temporal and steady-state characteristics of the relaxation term are compared to those of the standard Fokker-Planck term. The relaxation term is judged invalid for energies greater than the excitation threshold. Author
