摘　　要：利用少有的共线快离子激光光谱学方法研究了LaⅡ的超精细结构 ,测量了 5d2 1G4 态→ 4f5d1F3 态的超精细结构光谱 ,分别得出了相应的磁偶极矩和电四极矩的超精细相互作用常数 .The knowledge of the hyperfine structure of 139 LaⅡ has been very poor until now.In our experiment,the atomic hyperfine structure spectra of 139 LaⅡ with 5d\+2 1G 4 and 4f5d \+1F\-3 configurations have been measured using collinear fast\|ion\|beam laser spectroscopy,and the magnetic dipole and electric quadrupole coupling constants were determined.
