论文摘要
基于三轴转子模型，讨论了三轴变形$γ$对均匀核中纯粹的摇动运动形式的影响。发现当$γ= 30^{\ circ} $用于能量光谱和电动四极转变概率的属性时，谐波近似是很好的，而当$γ$从$ 30^{\ circ} $偏离时，此近似值会变得不良。研究了库仑激发实验的最新数据，即$ 3_1^+$和$ 2_2^+$的$^{110} $ ru的$ 2_2^+$。此外，方位图展示了两种类型的角动动量用于摇摆运动的角度几何形状，这是由于不同的$γ$值。
The influence of triaxial deformation $γ$ 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 $γ=30^{\circ}$ for the properties of energy spectra and electric quadrupole transition probabilities, while this approximation gets bad when $γ$ 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 $γ$ values, are exhibited by azimuthal plots.
