摘要
在本文中,认为价核子对相当于轨道角动量为0,2或4,自旋同位旋组合为s=0,τ=1或s=1,τ=0的玻色子,由这些玻色子所组成的体系的最大对称性群为U(90)。我们给出了群链U(90)U_(15)(sdg)×U_6(ST)SU_(15)(sdg)×U_6(ST)。SU_3(sdg)×SU_3(S)×SU_3(T)SU_3(sdgS)×O_3(T)。O_3(J)×O_3(T)的约化规则,典型能谱和具有这种动力学对称性的例子:^(24)Mg,并将我们的计算结果与实验数据及其他作者的计算结果进行了比较。在我们的计算结果中出现1^+态。
In this paper, the pairs of valence nucleons are thought to behave like bosons with angular momentum 0, 2, or 4, their total spin s and isospin τ=0 are in the combinations s=0, τ=1, or s=1, τ=0. The largest symmetric group of the system which is composed of these bosons is U(90). In the group chain U(90)U_(15)(sdg)×U_6(ST)SU_(15)(sdg)×U_6(ST)SU_3(sdg)×SU_3(S)×SU_3(T)SU_3(sdgS)×O_3(T)O_3(J)×O_3(T), this paper obtains the reduction rules, the typical energy spectra arid an example(^(24)Mg)with this dynamical symmetry. In this paper, the calculated result by us and the experimental data are compared with the calculated results by others. The state 1^+ appears in our calculated result.
