摘要:

该模型,介绍了在以前的文件中,八极和四极自由度的条件接近轴对称的描述,适用于形状相变的情况下,四极振幅可以达到零。在此模型框架下讨论了过渡核~(224)、~(226)Ra和~(224)Th。他们的能级方案可以合理地解释为假设一个二维方阱势。电磁跃迁振幅也进行了评估,并与现有的实验数据进行了比较。

英文摘要:

The model, introduced in a previous paper, for the description of the octupole and quadrupole degrees of freedom in conditions close to the axial symmetry, is applied to situations of shape phase transitions where the quadrupole amplitude can reach zero. The transitional nuclei 224,226Ra and 224Th are discussed in the frame of this model. Their level schemes can be reasonably accounted for assuming a square-well potential in two dimensions. Electromagnetic transition amplitudes are also evaluated and compared with existing experimental data.
