Abstract
Theoretical investigations of K-shell Δn = 1 (1s → 2l) dielectronic recombination (DR) of B-like Ar13+ ions are performed. The resonance energies, autoionization and radiative rates, as well as DR strengths, are obtained with inclusion of Breit and QED corrections using the Flexible Atomic Code. Furthermore, the differential cross sections, linear polarization, and polarization-dependent spectra for KLL DR process are presented for X-ray dielectronic satellite lines. The present results indicate the importance of high-order trielectronic and quadruelectronic recombination.
