Program package for semi-empirical analysis of the fine- and hyperfine structure of complex atoms — •Jerzy Dembczyński, Jaroslaw Ruczkowski, and Magdalena Elantkowska for the Dembczynski collaboration — Chair of Quantum Engineering and Metrology, Poznan University of Technology, Nieszawska 13B, 60-965 Poznan, Poland

The experimental work combined with semi-empirical calculations is a very efficient tool for the investigations of the fine- and hyperfine structure of the complex atoms.

We present a set of programs for the analysis of the fine- and hyperfine structure. The input data for the calculations are : the fine structure energy levels, the g_J-factors and the hyperfine structure (hfs) A and B constants of experimentally observed levels.

The programs are used for the analysis of electron systems containing any number of configurations up to four open shells. In the energy matrix generated, all kinds of electrostatic, magnetic and correlated electrostatic and magnetic interaction, up to second order perturbation theory, were included.

As a result, we obtain predicted energy values for all the levels of the system considered, their exact spectroscopic description and also g_J-factors and hfs A and B constants.
