Nicht-thermische Besetzungsdichten im Wasserstoffplasma mit Strahlungsabsorption
Steady-state population densities and electron densities are calculated in a non-equilibrium hydrogen plasma at constant pressure. The ratio of the temperatures of electrons and heavy particles is taken as a parameter. The radiation field of the LYMAN lines is included using a mean absorption coefficient for each transition. The deviations of densities of excited levels and electrons from equilibrium values are very large at low temperatures. The ground state population remains closer to equilibrium until the resonance radiation field vanishes with increasing temperature. Deviations from equilibrium are found to be present even at atmospheric pressure. Detailed results are shown in numerous diagrams for pressures from 0.01 to 1 atmosphere and electron temperatures from 5 × 103 to 4×104°K.
