2 Jan 2022 | | Abstract: | The reported transverse wobbling band in odd-mass $^{105}$Pd has been
reinvestigated by the triaxial particle rotor model. Employing several
different parameter sets of moment of inertia (MOI), all of the calculations
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, the axis which the total angular momentum wobbles about is changed from
the short axis to the intermediate axis. The obtained oscillation modes from
calculations are found to be the quantum tunneling between two orientations of
angular momentum, which is different from the expected precession. The
mechanism of rotational bands in $^{105}$Pd might be a competition between
different modes, which show the complexity of the transverse wobbling mode in
real odd-mass nuclei. | | Source: | arXiv, 2201.00279 | | Services: | Forum | Review | PDF | Favorites | |
