Calculation of the position of spectral lines in the intermediate coupling approximation taking into account the interaction of configurations
Abstract:
When modeling experimental spectra, special attention is paid to the accuracy of the position of spectral lines, which in many-electron ions depends not only on the spin-orbital and electrostatic interaction, but also on the interaction of configurations. In order to improve the THERMOS complex on the basis of an intermediate-type bond, a module was developed that uses the Ritz method to calculate the splitting of ion levels due to the spin-orbit interaction, taking into account the interaction of configurations. Comparisons of the results obtained for lithium and iron plasma are made.
