Natural radiative lifetime of Yb in the perturbed 6snd 1 ,3 D2 sequences
Jiang Zhankui, Chengfei Wang, Dadi Wang
Natural radiative lifetimes of ytterbium in the 6snd ${}^{1}$${D}_{2}$ (n=10--29), 6snd ${}^{3}$${D}_{2}$ (n=10--20) Rydberg sequences have been measured using stepwise excitation and a fluorescence-decay monitoring method. The lifetimes are perturbed by the 4${f}^{13}$5d6s6p configuration near n=11 and 27, except when the ${n}^{\mathrm{*}3}$ dependence of the lifetime values appeared. The lifetimes of the perturbing 5d6s6p states were also measured.
