摘　　要：利用共线快离子束 激光光谱学方法测量了正一价镨离子波长 5 81.6 9nm谱线的超精细结构光谱 ,得到了超精细相互作用常数 ;与已发表的数据比较 ,在测量误差范围内一致 。The hyperfine structure spectrum in 581.69 nm line of 141 Pr + was measured by collinear fast ion beam laser spectroscopy and the hyperfine coupling constants of the involved levels were deduced. Compared with the published data, our results are agreement with these data in the measurement uncertainty, but are improved by one order of magnitude
