The influence of triaxial deformation γ on the purely collective form of wobbling motion in even–even nuclei is discussed based on the triaxial rotor model. It is found that the harmonic approximation is realized well when the value γ = 30 is adopted for the properties of energy spectra and electric quadrupole transition probabilities, while this approximation gets worse when γ gradually deviates from 30. Recent data from a Coulomb excitation experiment, namely and for ¹¹⁰Ru, 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 the azimuthal plots.

基于三轴转子模型讨论了三轴变形γ对偶偶核中摆动运动的纯集体形式的影响。发现当能量谱性质和电四极子跃迁概率取γ = 30时，谐波近似可以很好地实现，而当γ逐渐偏离 30时，这种近似变得更糟。 库仑激发实验的最新数据，即和为¹¹⁰茹，进行研究，并可能会被建议作为摆动带的bandhead。此外，摆动运动的两种角动量几何，源于不同的γ 值，由方位图显示。
