摘要 探讨了在实际原子核体系中存在的区分中子-质子的SO(6)动力学对称性,并利用这种动力学对称性对过渡区的偶-偶核Xe,Ba和Ce等同位素的低激发谱进行了研究.所得理论结果与实验数据相符合. The present paper deals with the SO(6) dynamical symmetry existing in a realistic.nuclear system where the neutron and proton degrees of freedom are considered separately. Using this dynam-ical symmetry we have evaluated the low-lying exclted energy spectra for even-even Xe, Ba and Ce nu-clides in the transitlonal region. The theoretically predicted results are in good agreement with the ex-perimental data.
