The influence of core fine-structure interactions on dielectronic recombination at low temperatures: B-like C, N and O recombined ions

The author uses the program AUTOSTRUCTURE to calculate configuration-mixing intermediate-coupling effective dielectronic recombination rate coefficients for the recombined ions C+ N2+ and O3+ at temperatures T=103-6.3*104 K. The author tabulates results for the quartet-quartet transition lines-these do not arise in LS coupling at low densities applicable to gaseous nebulae-as well as selected doublet-doublet lines. The author also compares total rate coefficients for both direct radiative recombination and dielectronic recombination, the latter being calculated in both LS and intermediate coupling.
