偶偶核高自旋态的微观研究（III）对同位素^（126）Ba，^（128）Ba和^（130）Ba的应用

The Microscopic Investigation of High-Spin States for Even-Even Nuclei(III)Application to isotopes￣(126)Ba,￣(128)Ba and￣(130)Ba

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 configurations and the effective nucleon-nucleon interactions,a microscopic approach is applied to study high-spin states for the isotopes 126Ba,128Ba and 130Ba.The low-lying states and the band built upon aligned(h11/2)proton pair configurations are considered.Energy levels and backbendings are reproduced well.For the yrast band,the dependence of the strength of interband interaction on the coupling operator is discussed.
