| 摘 要： | 应用SO（6）的高阶项Q（0）×Q（0）×Q（0）]（0）代替SU（3）的四极-四极相互作用研究了176 Os和178 Os核的性质.首先研究了能谱和能级比,并和实验结果进行了对比,发现用SO（6）的高阶项代替SU（3）的四极-四极相互作用可以更好地符合实验数据.在此基础上,进一步研究了同带跃迁和异带跃迁B（E2）的比,结果表明,用SO（6）的高阶项可以更好地符合X（5）核特征.

| Abstract: | The SU(3) quadrupole-quadrupole interaction is replaced by the SO(6) cubic interaction Q(0)×Q(0)×Q(0)](0) to study the properties of 176Os and178Os nuclei.The energy levels and energy ratios are firstly investigated and compared with the experimental data.We find that the results can be improved by using the SO(6) cubic interaction.Then the B(E2) ratios for intra-band and inter-band transitions are further studied.The results show that the SO(6) cubic interaction can better describe the characters of X(5) nuclei than the SU(3) quadrupole-quadrupole interaction. |
