Abstract

Lβ₂ X-ray satellite spectra of tungsten and gold are calculated using the Multi-Configuration Dirac-Fock energies and compared with recent experimental data. New calculations of L₁-L₃M₅ Coster-Kronig transition energies for tungsten are presented, confirming the origin of the Lβ₂ visible satellites reported by two experimental groups. We found the value 5.09 eV for the average energy of the L₁-L₃M₅ Coster-Kronig transition in tungsten. The Lβ₂ satellite spectrum of tungsten was calculated in the framework of a statistical model, which makes use of Racah's algebra. A detailed calculation of the Lβ₂ and Lβ₁₅ satellite spectra was performed for gold.
