摘　　要：用两束圆偏振光和一束线偏振光实现三步激发得到Yb原子的6snp各里德堡系列的谱图,并利用磁量子数的选择定则确定了各条谱线所代表的原子态的总角动量量子数J.另外,还首次测得6sns ~3S_1(n=26～31)的能级数据.The spetrum for the 6snp Rydberg series of Yb Atom were obtained by using three-step laser excitation. The laser for the first and second step of exoi-tation were oppositely circularly polarized and for the third step was linearly polarized. By the selection rules of the magnetic quantum number m the J value for each spectral line was determined. Some new levels belonging to the 6sns 3Si series (n = 26-31) were detected.
