Relativistic Radiative and Auger Rates for Fe xxiv
نویسنده
چکیده
As part of a project to compute improved atomic data for the spectral modeling of iron K lines, we report extensive calculations and comparisons of radiative and Auger rates for transitions involving the K-vacancy states in Fe xxiv. By making use of several computational codes, a detailed study is carried out of orbital representations, configuration interaction, relativistic corrections, cancellation effects, and fine tuning. It is shown that a formal treatment of the Breit interaction is essential to render the important magnetic correlations that take part in the decay pathways of this ion. As a result, the accuracy of the present A-values is firmly ranked at better than 10% while that of the Auger rates at only 15%.

Photoionization and recombination cross sections and rate coefficients are calculated for Li-like Fe XXIV and He-like Fe XXV using the Breit-Pauli R-matrix (BPRM) method. A complete set of total and level-specific parameters is obtained to enable X-ray photoionization and spectral modeling. The ab initio calculations for the unified (e + ion) recombination rate coefficients include both the non...
متن کاملModeling of iron K lines : radiative and Auger decay data for Fe – Fe
A detailed analysis of the radiative and Auger de-excitation channels of K-shell vacancy states in Fe –Fe 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 Kα 2 /Kα 1 , Kβ/Kα, KLM/KLL,...

We report extensive calculations of the decay properties of fine-structure K-vacancy levels in Fe –Fe. 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 , and the Breit–Pauli R-matrix package. This multi-code approach is used to the study the effects o...
متن کاملRadiative and Auger Decay Data for Modeling Nickel K Lines
Radiative and Auger decay data have been calculated for modeling the K lines in ions of the nickel isonuclear sequence, from Ni up to Ni27+. Level energies, transition wavelengths, radiative transition probabilities, and radiative and Auger widths have been determined using Cowan’s Hartree-Fock with relativistic corrections (HFR) method. Auger widths for the third-row ions (NiYNi10+) have been ...
