Modeling of iron K lines: Radiative and Auger decay data for

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 finestructure levels populated by photoionization of the ground state of the parent ion. Different branching ratios, namely K (alpha) 2/K (alpha)1, K(beta)/K (alpha), KLM/KLL, KMM/KLL, and the total K-shell fluorescence yields, (omega) 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 K (alpha)2
