Fine- and hyperfine structure analysis of the even configuration system of tantalum atom — •Jerzy Dembczynski1, Magdalena Elantkowska1, Jaroslaw Ruczkowski1, and Laurentius Windholz2 — 1Chair of Atomic Physics, Poznan University of Technology, Nieszawska 13, PL-60-965 Poznan, Poland — 2Institute of Experimental Physics, Graz University of Technology, Petersgasse 16, 8010 Graz, Austria
The experimental work of L.Windholz and co-workers, concerning observation of the tantalum spectrum, yield many informations about new energy levels and hyperfine structure splittings. In this report the new findings are presented on the systematic studies of the tantalum atom and ion performed last years. We contribute the results of the complex parametric studies of the fine- and hyperfine structure of the mentioned element up to second-order of perturbation theory. The work has been performed for the systems including at least 23 configurations. The values of the radial parameters describing the one- and many-body interactions effects on atomic structure are given. We predicted values of energy levels and their A- and B- hyperfine structure constants, also for experimentally levels not observed up to now.
