Under the auspices of the IAEA Atomic and Molecular Data Center and the Korean Atomic Energy Research Institute, our assembled group of authors has reviewed the current state of dielectronic recombination (DR) rate coefficients for various ion stages of tungsten (W). Subsequent recommendations were based upon available experimental data, first-principle calculations carried out in support of this paper and from available recombination data within existing atomic databases. If a recommendation was possible, data were compiled, evaluated and fitted to a functional form with associated uncertainty information retained, where available. This paper also considers the variation of the W fractional abundance due to the underlying atomic data when employing different data sets.

在国际原子能机构原子与分子数据中心和韩国原子能研究院的主持下，由我们组成的小组审查了钨（W）各个离子阶段的双电子复合（DR）速率系数的当前状态。随后的建议是基于可用的实验数据，为支持本文而进行的第一性原理计算以及现有原子数据库中的可用重组数据。如果有可能提出建议，则将数据汇编，评估并拟合为功能形式，并在可能的情况下保留相关的不确定性信息。本文还考虑了使用不同数据集时由于基础原子数据导致的W分数丰度的变化。
