Abstract
Extensive multiconfiguration Dirac-Fock calculations with the inclusion of the transverse (Breit) interaction and QED corrections have been carried out on gold and thorium to elucidate the structure of various satellite (additional vacancies in N and/or O shells) and hypersatellite (additional vacancies in M or M and N shells) Mα1,2 (M5N6,7) and Mβ1 (M4N6) lines in its X-ray spectra. For every calculated type of Mα1,2 and Mβ 1 lines the theoretical stick spectra (line positions with their relative intensities) have been presented. Moreover for each type of lines two theoretical spectra have been predicted: one being a sum of the Lorentzian natural line shapes and the other one being a convolution of the sum of the Lorentzian natural line shapes with the Gaussian instrumental response. The obtained results will be very helpful in quantitative interpretation of a very complex origin of Mα 1,2 and Mβ 1 line structures in various high-resolution X-ray spectra of heavy atoms induced by different light and heavy projectiles.
