Abstract
Recombination rates in ion plasma are presented that are obtained by processing experimental data on gas discharge afterglow in fluorine and sulfur hexafluoride media. A theoretical explanation is given to the slowing down of the recombination rate of plasma in such media as the degree of Coulomb nonideality of the media increases. An additional factor for the suppression of recombination—solvation of ions—is considered. It is shown that, in the case of discharge afterglow plasma in a fluorine medium, the process of recombination proceeds in two stages with the formation of intermediate metastable ion pairs produced by ion-molecule clusters. In a sulfur hexafluoride medium, the formation of such pairs does not have a significant effect on the recombination rate.
