摘　　要：利用共线快离子束 激光高分辨光谱学方法测量了14 3 ,14 5Nd+ 5 70 38nm谱线的超精细结构光谱 ,并得到了参与跃迁的上、下能级的超精细相互作用常数。Hyperfine structure in atomic ions is caused by the electromagnetic interaction between the nucleus and orbital electrons.Information on the nuclear structure and also on the electronic properties of ions can be obtained through studying the hyperfine structure.Hyperfine structure spectrum in the 570 38 nm line of 143,145 Nd + was measured by using collinear fast ion beam laser spectroscopy.All the spectral lines were resolved and the magnetic dipole and electric quadrupole coupling constants of the corresponding metastable levels and excited levels were determined.
