Ionization and recombination coefficients for a dense nonideal hydrogen plasma: effects of screening and degeneracy

Rate equations are derived for a strongly coupled hydrogen plasma starting from a generalized kinetic equation which accounts for chemical reactions and many-particle effects. The impact ionization and three-body recombination coefficients are calculated taking into account effective interaction potentials, self-energy shifts and Pauli-blocking. The density dependence is discussed which follows for the ionization as well as for the recombination coefficients.
