I/xxx Modeling of the iron K lines: radiative and Auger decay data for Fe II-Fe IX (Palmeri+ 2003) =============================================================================== Modeling of the iron K lines: radiative and Auger decay data for Fe II-Fe IX Palmeri P., Mendoza C., Kallman T.R., Bautista M.A., Melendez M. =2003A&A...x...x =============================================================================== Keywords: atomic data-atomic processes-X-rays: spectroscopy Abstract: 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. 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/K-alpha_1 ratio is found to be sensitive to the excitation mechanism. From these comparisons it has been possible to estimate an accuracy of ~10% for the present transition probabilities.
