The stability of the general analytical solutions of a collisional-radiative model, for nonequilibrium, partially ionized, steady-state argon plasma, is examined. The model includes three atomic energy levels: the ground level, one excited level, and the continuum. A Maxwellian electron distribution function is also assumed. This model was previously considered by Braun and Kunc [Phys. Fluids {bold 30}, 671 (1987)]. All the rates for collisional-radiative processes and diffusion losses are expressed as analytical functions. The model is solved for the electron and excited atom densities in two plasma regimes, with and without diffusion losses. Transitions between these two possibilities are also discussed. {copyright} {ital 1995} {ital American} {ital Institute} {ital of} {ital Physics}.
