摘要: The hyperfine structure of the $6snd^{1}D_{2}$ ($10l~nl~50$) Rydberg states barium has been measured and analyzed in terms singlet-triplet mixing. A dispersionlike resonant behavior mixing coefficient $\ensuremath{\Omega}$ was observed for strontium vicinity doubly excited configurations. In strong disagreement with multichannel-quantum-defect-theory wave functions found. present results are compared spin polarization anisotropy photoelectrons.
