Influence of moments of inertia on transverse wobbling mode in odd-mass nuclei

Abstract

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.
