摘要: 近年来,通过对已知正常形变核转动带的分析,发现了“等同带”(即具有惊人相似的转动惯量),本文利用一个严格的判据,比较了A=150～190质量区奇A核及其相邻A—1偶—偶核的转动带,发现“等同带”对应于奇A核中占据上升轨道的粒子态。这意味着,“等同带”的出现可能是由于对关联减弱和形变减小两者对转动惯量的影响相互抵消的结果。 "Identical bands" (i. e. those with surprisingly similar moments of inertia) have beenfound through several analyses of known bands in normally deformed nuclei. In this paper, we analyzebands in odd-proton nuclei (A=150～190) and A-1 even-even adjacent nuclei with stringentcriteria. The "identical bands" are found to be associated with upsloping particle states. Therefore thecause of occuring "identical bands" may be a cancellation of effects on the moment of inertia betweenpairing and....
