在对截断壳模型的框架内，对Ba，Ba，Ce和Nd同位素进行了系统的研究，其中角动量为0和2的集体核子对被假定为偶偶核的积木。为了描述奇质量核，在偶-偶核中增加了一个额外的未成对核子。结果表明，低激发态的能谱随带内和带间跃迁的沿着很好地再现，模拟了相互作用玻色子模型O（6）极限的典型特征.
Systematic studies are carried out for Xe, Ba, Ce, and Nd isotopes within the framework of the pair-truncated shell model where the collective nucleon pairs with angular momenta zeroand twoare assumed to be the building blocks for even-even nuclei. An additional unpaired nucleon is added to the even-even core for a description of odd-mass nuclei. It is found that energy spectra of the low-lying states are nicely reproduced along with intraband and interbandtransitions, which simulate the typical features of the O(6) limit of the interacting boson model.
