双电子（DR）和辐射（RR）的复合速率系数为19磷类离子，S+和W 59+之间，形成硫类离子，已被计算为组装的一部分的水平分辨数据库建模动态有限密度等离子体，在广义碰撞辐射框架。计算已在多配置Breit-Pauli近似使用代码AUTOSTRUCTURE，从地面和亚稳态的初始状态，在LS耦合和中间耦合（IC），允许从地面和亚稳态水平的核心激发在DR过程中所涉及到的EAN = 0和EAN = 1。计算了S ~+、Zn ~（15）+、K ~（21）+、Mo ~（27）+、Xe ~（39）+和W ~（59）+的部分和总DR系数。本文讨论了从序列中选择离子的结果，并与现有的理论和实验结果进行了比较。Fe 11+共振谱与FPN = 0核心激发的双电子复合结果进行了比较，从合并束测量。总（IC）DR和RR率系数的拟合以表格形式呈现。部分LS和IC DR和RR速率系数分别以标准ADAS adf 09和adf 48文件格式存档在开放存取数据库OPEN-ADAS中。
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.
