摘　　要：原子光谱中 ,同位素位移是少数几个能够将原子物理学和原子核物理学这两个不同的物理学分支联系起来的课题之一 .本文利用共线快离子束 激光光谱学方法 ,测量了正一价钕离子所有 7个稳定同位素 (A =142— 146 ,148,15 0 )之间的能量位移 .与已有的结果比较 。In atomic spectroscopy, the subject of isotope shifts is one of the few problems that links atomic and nuclear physics. The isotope shifts among all the seven stable isotopes in Nd Ⅱ were measured by means of collinear fast\|ion\|beam laser spectroscopy.Compared with the data that have been published,our experimental accuracy is improved by one order of magnitude and some of the results are obtained for the first time, as far as we know.
