Fine- and hyperfine structure analysis of the odd configuration system of Ta II — •Jerzy Dembczynski1, Jaroslaw Ruczkowski1, Magdalena Elantkowska1, 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 fine structure of the odd levels of the single ionised tantalum has been analyzed by simultaneous parametrization of one- and two-body interactions for the system of 23 configurations:
5d3n’f (n’=5-7) + 5d3n"p (n"=6-10) + 5d26sn’f (n’=5-7) + 5d26sn"p (n"=6-10) + 5d26p7s + 5d5f6s2 + 5d6s26p + 5d6s27p + 5d6s6p7s + 5d6s6p6d + 5d6p3.
The analysis was stimulated by the new experimental data obtained by L.Windholz and co-workers. Magnetic-dipole hyperfine interaction constants A were calculated using the fine structure eigenvectors and adjusting radial integrals in a least-squares procedure which compare the calculated A constants with the experimental values. Moreover, the values of energy for the levels up to now unidentified and hyperfine structure A constants were predicted.
