论文摘要
在相互作用的玻色子模型的框架内，基于SU（3）代数理论，根据SU（3）代数理论鉴定并分析了三重核核的异常低能$ E2 $相关行为。结果显示出惊人的功能，其中包括$ b（e2; 4_1^+\ rightArrow2_1^+）/b（2_1^+\ rightArrow0_1^+）<1.0 $过渡率比和a $ e（4_1^+）/e（4_1^+）/e（2_1^+）> 2.0 $ the $ limition $ limition $ n $ n $ n $ n $ n $ n。对于稳定的$γ$定义会产生正常结果。该描述显示出在中子缺陷核中观察到的$ e2 $异常现象，例如$^{172} $ pt和$^{168} $ OS，因此，这样做可以更深入地了解柔软的三方构成核的物理特征。
The anomalous low-energy $E2$-related behavior of a triaxially-deformed nucleus bas been identified and analyzed based on the SU(3) algebraic theory within the framework of the interacting boson model. The results show striking features that include a $B(E2;4_1^+\rightarrow2_1^+)/B(2_1^+\rightarrow0_1^+)<1.0$ transition rate ratio and a $E(4_1^+)/E(2_1^+)>2.0$ excitation energy ratio that can be tracked back to a finite-$N$ effect, which in a large-$N$ limit of the theory yields normal results for a stable $γ$-deformation. This description is shown to be able to explain observed $E2$ anomalous phenomenon in neutron-deficient nuclei such as $^{172}$Pt and $^{168}$Os, and in so doing yields a deeper understanding of the physical features of a soft triaxially-deformed nucleus.
