On Dielectronic Recombination
The derivation of a general formula for the coefficient of dielectric recombination is reviewed, and approximate formulae known in the literature are discussed. With the aid of Burgess' simplified formula calculations of the coefficient of dielectronic recombination for the elements C, 0 , Ne, M g , Si, S and Fe in the temperature range 108 — 4 x 106 ° K are performed. The results are presented...

متن کاملDielectronic Recombination Calculations for Fe
Dielectronic recombination (DR) of Na-like Fe forming Mg-like Fe via excitation of a 2l core electron has been investigated. We find that configuration interaction (CI) between DR resonances with different captured electron principal quantum numbers n can lead to a significant reduction in resonance strengths for n ≥ 5. Including this form of CI accounts for most of the discrepancy between prev...
متن کاملDielectronic recombination for boronlike ions
We have calculated the total dielectronic recombination ~DR! coefficients for the P1/2 and P3/2 states in B-like Ti, Fe, and Mo ions for electron temperatures 0.1<T<10 000 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 determi...
متن کاملDielectronic Recombination In Active Galactic Nuclei
XMM-Newton and Chandra observations of active galactic nuclei (AGN) show rich spectra of X-ray absorption lines. These observations have detected a broad unresolved transition array (UTA) between ∼ 15-17 Å. This is attributed to inner-shell photoexcitation of M-shell iron ions. Modeling these UTA features is currently limited by uncertainties in the low-temperature dielectronic recombination (D...
