摘要
用两步激发和光电离方法,在0-1500V/cm 电场范围内,测定了Yb原子n=17至n=20附近.m=0和|m|=1的Stark光谱.采用数值积分方法对实验研究范围内的Stark能级结构作了计算,理论与实验结果基本符合.讨论了电场中能级的抗交叉行为及其与量子亏损的关系,并对m=0和|m|=1两种Stark能级结构的特点作了比较.
The Stark spectra of Yb atom with m=0 and |m|=1 in the vicinity of n=17 to n=20 have been obtained by using two-step excitation and photoioni-zation method in the applied electric field from 0 to l500V/cm. The Stark splittings and shifts observed in the experiment have been calculated by using numerical integration method. The thoretical results are consistent generally with the experiments. The dependence of the anticrossings of Stark manifolds with quantum defects is investigated. The comparison between the m=0 and |m|=1 Stark structures is furnished.
