【 摘 要 】

Theoretical studies of Rydberg autoionization resonances in spectra of lanthanides atoms (ytterbium) are carried out within the relativistic many-body perturbation theory in the generalized relativistic energy approach (Gell-Mann and Low S-matrix formalism). The accurate theoretical results on the autoionization 4f13[2F7/2]6s2np[5/2]2, 4f13[2F7/2] 6s2nf[5/2]2resonances energies and widths are presented and compared with experimental data, obtained by using laser polarization spectroscopy method.
