Abstract
Dielectronic (DR) and radiative (RR) recombination rate coefficients for 19 phosphorous-like ions, between S+ and W59+, forming sulphur-like ions, have been calculated as part of the assembly of a level-resolved database necessary for modelling dynamic finite-density plasmas, within the generalized collisional-radiative framework. Calculations have been performed within the multi-configuration Breit-Pauli approximation using the code AUTOSTRUCTURE, from both ground and metastable initial states, in both LS coupling and intermediate coupling (IC), allowing for ∆n = 0 and ∆n = 1 core-excitations from the ground and metastable levels involved in the DR processes. Partial and total DR coefficients have been calculated for S+ to Zn15+, as well as Kr21+, Mo27+, Xe39+, and W59+. Results for a selection of ions from the sequence are discussed in this paper, and are compared with the existing theoretical and experimental results. Dielectronic recombination results for the Fe11+ resonance spectrum associated with ∆n = 0 core excitations are compared with those from merged-beam measurements. Fits to the total (IC) DR and RR rate coefficients are presented in tabular form. Partial LS and IC DR and RR rate coefficients are archived in the open access database OPEN-ADAS in standard ADAS adf09 and adf48 file formats, respectively.
