Abstract

Dielectronic recombination (DR) rate coefficients for 22 sodium-like ions, between Mg⁺ and Xe⁴³⁺, forming magnesium-like ions have been calculated as part of the assembly of a level-resolved DR database necessary for modelling dynamic finite-density plasmas, within the generalized collisional–radiative framework. Calculations have been performed from both ground and metastable initial states, in both LS- and intermediate coupling, allowing for and core-excitations from ground and metastable levels. Partial and total DR coefficients have been calculated for Mg⁺ to Zn¹⁹⁺, as well as Kr²⁵⁺, Mo³¹⁺, and Xe⁴³⁺. Results for a selection of ions from the sequence are discussed in the paper and compared with existing theoretical and experimental results. A full set of results can be accessed from the Atomic Data and Analysis Structure (ADAS) database or from the Oak Ridge Controlled Fusion Atomic Data Center (http://www-cfadc.phy.ornl.gov/data_and_codes).
