摘要

基于三轴转子模型，讨论了三轴形变对偶偶核纯集体摆动运动的影响。发现当$\gamma$ =30^{\circ}$时，能谱和电四极跃迁概率的性质可以很好地实现谐波近似，而当$\gamma$偏离$30^{\circ}$时，这种近似就变差了。本文研究了库仑激发实验的最新数据，即$^{110}$Ru的$3_1^+$和$2_2^+$，并认为它们可能是摆动带的带头。此外，还通过方位角图展示了两种由不同$\gamma$值引起的摆振运动的角动量几何。

Influence of triaxial deformation on wobbling motion in even–even nuclei

The influence of triaxial deformation $\gamma$ on the purely collective form of wobbling motion in even-even nuclei are discussed based on the triaxial rotor model. It is found that the harmonic approximation is realized well when $\gamma=30^{\circ}$ for the properties of energy spectra and electric quadrupole transition probabilities, while this approximation gets bad when $\gamma$ deviates from $30^{\circ}$. A recent data from Coulomb excitation experiment, namely $3_1^+$ and $2_2^+$ for the $^{110}$Ru are studied and might be suggested as the bandhead of the wobbling bands. In addition, two types of angular momentum geometries for wobbling motion, stemming from different $\gamma$ values, are exhibited by azimuthal plots.
