We report extensive calculations of the decay properties of fine-structure K-vacancy levels in Fe x –Fe xvii .
A large set of level energies , wavelengths , radiative and Auger rates , and fluorescence yields has been computed using three different standard atomic codes , namely Cowan ’ s hfr , autostructure and the Breit–Pauli R-matrix package .
This multi-code approach is used to the study the effects of core relaxation , configuration interaction and the Breit interaction , and enables the estimate of statistical accuracy ratings .
The K \alpha and KLL Auger widths have been found to be nearly independent of both the outer-electron configuration and electron occupancy keeping a constant ratio of 1.53 \pm 0.06 .
By comparing with previous theoretical and measured wavelengths , the accuracy of the present set is determined to be within 2 mÅ .
Also , the good agreement found between the different radiative and Auger data sets that have been computed allow us to propose with confidence an accuracy rating of 20 % for the line fluorescence yields greater than 0.01 .
Emission and absorption spectral features are predicted finding good correlation with measurements in both laboratory and astrophysical plasmas .
