Collective correlation and screening effects on radiative recombination in classical nonideal plasmas

Abstract

Collective correlation and plasma screening effects on the K-shell radiative recombination of the free electron with the ion in classical nonideal plasmas are investigated. The radiative recombination cross section is obtained by the principle of detailed balance with the photoionization cross section of the hydrogenic ion in nonideal plasmas. It is found that the collective and plasma screening effects significantly reduce the radiative recombination cross section in nonideal plasmas. It is also found that the collective and screening effects on the recombination cross section is almost independent of the projectile energy.
