Dielectronic satellite spectra of hydrogenlike chromium

Abstract

Calculations of atomic parameters for dielectronic satellite lines of hydrogenlike chromium have been performed in the intermediate-coupling scheme with the inclusion of effects of configuration interaction. The doubly excited intermediate resonance states considered are ‖2l nl’ SLJ〉, n=2, 3, and 4 with all allowed values of l and l’. The Hartree-Fock-Slater atomic model is used to calculate transition rates. X-ray and Auger transition energies are corrected for relativistic effects. Radiative and radiationless transition rates, fluorescence yields, nonradiative branching ratio, and lifetime of these doubly excited states are reported. For the wavelengths of a few strong satellite lines, effects of self-energy and vacuum polarization are included in our calculation. Dielectronic recombination rate coefficients are presented as a function of electron temperature.
