A triaxial core rotating around the middle axis, i.e. two-axis, is cranked around the one-axis, due to the coupling of an odd proton from a high j orbital. Using the Bargmann representation of a new and complex boson expansion of the angular momentum components, the eigenvalue equation of the model Hamiltonian acquires a Schrdinger form with a fully separated kinetic energy. From a critical angular momentum, the potential energy term exhibits three minima, two of them being degenerate. Spectra of the deepest wells reflects a chiral-like structure. Energies corresponding to the deepest and local minima respectively, are analytically expressed within a harmonic approximation. Based on a classical analysis, a phase diagram is constructed. It is also shown that the transverse wobbling mode is unstable. The wobbling frequencies corresponding to the deepest minimum are used to quantitatively describe the wobbling properties in 135Pr. Both energies and e.m. transition probabilities are described.

玻色子在奇偶核中摆动的新方法

由于奇数质子与高j的耦合,绕中轴(即两轴)旋转的三轴核心绕单轴转动。轨道。使用角动量分量的新的复杂玻色子展开的Bargmann表示,哈密顿量模型的特征值方程获得具有完全分离的动能的Schrdinger形式。从临界角动量来看,势能项显示三个最小值,其中两个退化。最深井的光谱反映出一种手性结构。分别对应于最深和局部极小值的能量在谐波近似中解析表示。在经典分析的基础上,构建了一个相图。还显示出横向摆动模式是不稳定的。对应于最深最小值的摆动频率用于定量描述135中的摆动特性公关 描述了能量和跃迁概率。
