从壳模型组态及核子－核子有效相互作用出发，借助于一种描述偶偶核高自旋态的微观理论方案，对同位素１２６Ｂａ，１２８Ｂａ和１３０Ｂａ的低能态及质子拆对占据ｈ１１／２侵入轨道所出现的回夸现象作了研究．得到了与实验定性符合较好的结果．对Ｙｒａｓｔ带，进一步探讨了带间相互作用强度与耦合算子之间的关系．
Starting from the shell model configuration and the effective nucleon-nucleus interaction, the low energy states and proton disassociation of isotopes 126Ba, 128Ba and 130Ba occupy the h11 / 2 invagination orbit due to a micro-theoretical scheme describing the high spin states of even and even nuclei The return of boast phenomenon made a study. The result is in good agreement with the experiment. For the Yrast zone, the relationship between the intensity of the interaction between bands and the coupling operator is further explored.
