摘      要：Wobbling motion in a system comprising a triaxial rotor and a single quasiparticle is studied employing the particle-rotor *** energy spectra,wobbling frequencies,electromagnetic transition probabilities,g-factors,angular momentum components,spin coherent state maps,and static quadrupole moments are *** investigations were conducted with regard to the Fermi surface transitioning from the lowest h_(11/2) orbit to the highest *** the Fermi surface increases,notable transformations occur in the wobbling ***,the mode exhibits a transverse revolution around the short axis of the ***,as the Fermi surface continues to increase,the mode gradually shifts to a longitudinal revolution around the intermediate ***,it transitions to a transverse revolution around the long ***,the stability of the long axis transverse mode diminishes relative to its counterpart along the short axis as the total angular momentum increases atγ=20∘.
