Relativistic configuration interaction calculations for the Kα and Kβ X-ray satellites of iron

Multi-configuration Dirac–Fock and relativistic configuration interaction calculations with the Breit interaction, quantum electrodynamics, and finite nuclear mass corrections were carried out in the extended optimal level scheme for the transition wavelengths, electric dipole transition rates, and oscillator strengths of the Kα and Kβ X-rays from Fe XVII through Fe XXV. The calculated values were compared with the available data on He-like, Li-like, Be-like, and F-like iron, and were in very good agreement. These data provide reference values for level lifetime, charge state distribution, and average charge of iron plasmas.
