Multiconfiguration Dirac-Fock calculations of dielectronic recombination coefficients for the He isoelectronic sequence
Dielectronic recombination coefficients for ground-state ions of the He isoelectronic sequence have been calculated for 13 ions, with atomic number 6< or =Z< or =42, in the isolated resonance approximation, for temperatures in the range 0.1< or =T< or =12 keV. The detailed Auger and radiative rates of the doubly excited states were evaluated by using the multiconfiguration Dirac-Fock model. The behavior of the dielectronic recombination coefficient along the isoelectronic sequence is examined. The effect of relativity drastically alters the dielectronic satellite structure of He-like FeSU and MoU . However, the relativistic effect reduces the total dielectronic coefficients for FeSU by only 10% and 2.5% at T = 0.5 and 5 keV, and for MoU by 18% and 5% at T = 2 and 5 keV, respectively.
