摘　　要：利用具有光谱高分辨和选择性激发等特点的共线快离子束激光光谱学方法研究了159Tb II亚稳态 4 f95 d7H08和激发态 4 f96 p3 / 2 ( 1 5 /2 ,3/2 )的超精细结构光谱 ,所有光谱线可以很好地分辨 ;并由实验测量到的高分辨超精细结构光谱 。The setup of the collinear fast ion-beam-laser spectroscopy (CFIBLS) with the Fabry-Prot interferometer is described and the method of analyzing the experimental data is given. The hyperfine structures of the transitions from metastable 4f 95d 7H 0 8 to excited states 4f 96p 3/2 (15/2, 3/2) for 159 TbII was measured by CFIBLS. For the high spectral (sub-Doppler) resolution of CFIBLS, the HFS constants A and B of the involved levels were obtained with small errors.
