摘要
在费米子动力学对称性模型的框架下对中重质量区原子核的十六极振动自由度给出了一种新的描述。本文详细讨论了k-active情形。导出了两种极限情况下的能谱公式,并就^(204)Pb的能谱计算与实验结果及sdg IBM理论的计算结果进行了比较。
A new description of the hexadecapole degree of freedom in the medium and heavy mass region in the framework of the Fermion Dynamical Symmetry Model (FDSM) is proposed. In this paper, the k-active case is discussed in detail, in which the pairing and multipole operators generate SP_(10) group. The energy spectra are derived for two limits of the pairing, quadrapole and hexadecapole strength. Finally, the spectra of ^(204)Pb are fitted and compared with the experimental values and the results obtained from sdg IBM.
