Influence of Nonideality Effects on the Ionization and Recombination Coefficients of a Reacting Hydrogen Plasma

On the basis of generalized quantum kinetic equations for chemically reacting systems which include many particle effects, the ionization and recombination coefficient of a dense hydrogen plasma are determined. Using a simple approximation for the continuum shift in the quasiparticle energies, nonideality effects are taken into account and lead to a nonlinear density dependence of the rate coefficients. In the case of thermodynamic equilibrium the rate equation yields a Saha equation for a nonideal plasma.
