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.

In this paper numerical simulation of the spectral properties of xenon plasma is carried out for various parameters (temperature, density, pressure) within the framework of the Saha-Boltzmann approximation. For calculations, pre-prepared atomic databases with varying degrees of detail of ion states were used. The effect of ionization potential depression was taken into account. The spectral absorption coefficients and emissivity, as well as the spectral radiation energy flux for a homogeneous plasma in a spherically symmetric geometry, were obtained. The identification of strong spectral lines in the wavelength ranges of interest has been carried out.
