摘要
按照转动带自旋指定的3种方案,分析了A ̄190区偶偶核中已测到的超变形带。对于194Hg(1)和194Pb(1),分析给出的自旋指定与实验值完全一致。有理由认为,其它10条超变形带的自旋指定也是可信的,否则要重新审查现有的转动谱理论,而这些理论对于正常形变核转动带已证明是完全正确的。
Using the three schemes for the spin assignment of rotational bands,thesuperdeformed bands of even-even nuclei observed in the A ̄190 region were analyzed.For the yrast SD bands 194Hg(1)and 194Pb(1),the spin assignment are consistent withthe experimental results.The spin assignment for the other SD bands in even-evennuclei (A ̄190)are also believed to be reliable.Otherwise,the validity of theavailable theory should be re-examined when applied to the superdeformed nuclei.
