Dielectronic recombination for boronlike ions

Savin, Daniel Wolf; Chen, M. H.; Reed, K. J.; Guo, D. S.

We have calculated the total dielectronic recombination (DR) coefficients for the 2P1/2 and 2P3/2 states in B-like Ti17+, Fe21+, and Mo37+ ions for electron temperatures 0.1<~T<~10000 eV. The calculations are carried out using the multiconfiguration Dirac-Fock method in intermediate coupling with a configuration interaction. We find that accurate Coster-Kronig energies are critical for a successful determination of low-temperature DR coefficients. We also find that the DR involving fine-structure excitations can be as important as the 2s-2p excitation channels in the low-temperature regime for some ions.
