Enhancement of Dielectronic Recombination by Plasma Electric Microfields

Abstract

An investigation has been made of the $l$-redistribution effect of quasistatic ion electric microfields on dielectronic recombination. Using the linear-Stark-effect approximation, a hydrogen ion density of ${10}^{14}$ ${\mathrm{cm}}^{-3\mathrm{}}$ is found to produce a threefold enhancement in the rate for the dielectronic recombination process ${\mathrm{Fe}}^{+23\mathrm{}}\mathrm{}\left(2s\right)+e^{-}\to {\mathrm{Fe}}^{+22\mathrm{}}(2p,nl)\to {\mathrm{Fe}}^{+22\mathrm{}}(2s,nl)+\hslash \omega$.
