Simplified Model for Ionization and Recombination in a Hydrogenic Plasma with Resonance Radiation Trapping

The rate coefficients for electron collisional-radiative ionization and recombination have been calculated on the basis of a simplified level scheme for hydrogenic ions in a homogeneous and fully contained plasma with self-absorption for (Doppler broadened) Lyman a radiation. The energy distribution of the electrons is assumed to be Maxwellian. Photoionization is neglected. The cal-culation have been done for a range of electron temperature of Z2 to 10 Z2 eV and electron density of 1014 Z7 to 1024 Z7 m-3 , where Z is the charge number of the bare nucleus.
