详细分析了feii - feix中k壳空位态的辐射通道和俄歇去激发通道。能级能，波长，a值，俄歇率和荧光产额已经计算的最低精细结构的能级由光电离的基态母离子填充。不同的分支比，即K2/K1、K /K、K LM/KLL、KMM/KLL，以及K壳层的总荧光产率！将本工作中得到的K值与其他理论数据和固体测量结果进行了比较，发现与后者基本一致。K2/K1比值对激发机制很敏感。从这些比较中，可以估计出目前转变概率的准确度为10%。
A detailed analysis of the radiative and Auger de-excitation channels of K-shell vacancy states in Fe ii-Fe ix has been carried out. Level energies, wavelengths, A-values, Auger rates and fluorescence yields have been calculated for the lowest fine-structure levels populated by photoionization of the ground state of the parent ion. Dierent branching ratios, namely K2/K1 ,K /K ,K LM/KLL, KMM/KLL, and the total K-shell fluorescence yields, !K, obtained in the present work have been compared with other theoretical data and solid-state measurements, finding good general agreement with the latter. The K2/K1 ratio is found to be sensitive to the excitation mechanism. From these comparisons it has been possible to estimate an accuracy of10% for the present transition probabilities.
