摘　　要：利用共线快离子束 激光高分辨光谱学测量了1 41 Pr+ 波长为 5 6 9 0 8nm谱线的超精细结构光谱 ,由此得到超精细相互作用常数和参与跃迁激发态、亚稳态能级的超精细能级分裂 .与已有的数据比较 ,在实验误差范围内一致 ,但测量精度提高了一个数量级 .Hyperfine structure spectrum in 569 08nm line of 141 Pr + was measured by the collinear fast ion beam laser spectroscopy. All the spectral lines were resolved. The magnetic dipole and electric quadruple coupling constants, and hyperfine splitting of the metastable levels and excited levels were determined. Our results were in agreement with the published data within experiment uncertainty. The accuracy of the magnetic dipole coupling constants was improved by one order of magnitude compared with the published data.
