在详细的不透明度计算中考虑高激发态
Accounting for highly excited states in detailed opacity calculations
摘要：
在多电荷离子等离子体中，大量电子可能占据高能轨道。这些“里德伯”电子，当它们作为观众时，负责X射线吸收或发射线的卫星，产生共振线的红翼加宽。这种卫星线的贡献可能是重要的，因为高简并的相关激发配置，使这些大玻尔兹曼权重。然而，通常难以考虑这些配置，因为它们可能产生大量的线。我们建议以类似于C.伊格莱西亚斯它包括在一个部分详细的线会计计算，其中的里德堡观众的影响包括通过移位和宽度，表示在规范的配分函数，这是关键成分的超级过渡阵列模型。由此产生的方法可以先验地用于任何详细配置/行会计不透明代码。
英文摘要：
In multiply-charged ion plasmas, a significant number of electrons may occupy high-energy orbitals. These "Rydberg" electrons, when they act as spectators, are responsible for a number of satellites of X-ray absorption or emission lines, yielding a broadening of the red wing of the resonance lines. The contribution of such satellite lines may be important, because of the high degeneracy of the relevant excited configurations which give these large Boltzmann weights. However, it is in general difficult to take these configurations into account since they are likely to give rise to a large number of lines. We propose to model the perturbation induced by the spectators in a way similar to the Partially-Resolved-Transition-Array approach recently published by C. Iglesias. It consists in a partial detailed-line-accounting calculation in which the effect of the Rydberg spectators is included through a shift and width, expressed in terms of the canonical partition functions, which are key-ingredients of the Super-Transition-Arrays model. The resulting method can a priori be used in any detailed-configuration/line-accounting opacity code.
