论文摘要
奇数$^{105} $ pd中报告的横向摇摆带已被三轴粒子转子模型重新测试。采用不同的惯性矩（MOI）的参数集，几个计算的结果可能与实验数据非常吻合，这些数据分别显示出不同的旋转激发模式。这些模式对中间和短轴的MOI之间的比率敏感。随着该比率的增加，围绕总角动量的短轴的摇摆逐渐变为中间轴的摇摆。此外，还表明进动和隧道是量子摇摆运动的两个方面。隧道方面在$^{105} $ pd的Yrare状态中占主导地位。目前的结果$^{105} $ PD显示了横向摇摆模式的复杂性。
The reported transverse wobbling band in odd-mass $^{105}$Pd has been reinvestigated by the triaxial particle rotor model. Employing different parameter sets of moment of inertia (MOI), several calculated results could be in good agreement with the experimental data, which show distinct modes of rotational excitation, respectively. These modes are sensitive to the ratio between the MOI at intermediate and short axis. With the increase of this ratio, a wobble about the short axis of the total angular momentum is gradually changed to a wobble about the intermediate axis. In addition, it is exhibited that precession and tunneling are two aspects of the quantum wobbling motion. The tunneling aspect dominates in the yrare states of $^{105}$Pd. The present results in $^{105}$Pd show the complexity of the transverse wobbling mode.
