论文摘要
我们考虑了SU（3）部分动态对称性的几种变体，相对于核中的四极形状。具有这种特性的汉密尔顿人的明确结构在相互作用的玻色子模型（IBM）的框架中介绍，包括高阶项及其质子 - 中子扩展（IBM-2）。考虑的案例包括具有可解决地面和$γ$或$β$频段的单个倾斜形式的形状，并存的底漆形状具有可溶的地面带，以及与可溶的蛋白质独立形状对齐，并与可解决的对称地面和$γ$ bands and Compy-Memmetry Scissors and $γ$ combanss和$γ$ cossors and $γ$γ$γ$γ$γ$γ$γ$。
We consider several variants of SU(3) partial dynamical symmetry in relation to quadrupole shapes in nuclei. Explicit construction of Hamiltonians with such property is presented in the framework of the interacting boson model (IBM), including higher order terms, and in its proton-neutron extension (IBM-2). The cases considered include a single prolate-deformed shape with solvable ground and $γ$ or $β$ bands, coexisting prolate-oblate shapes with solvable ground bands, and aligned axially-deformed proton-neutron shapes with solvable symmetric ground and $γ$ bands and mixed-symmetry scissors and $γ$ bands.
