“…At the same time, these calculations predicted Q = −1.25 eb. The distribution of the quadrupole moment expectation values obtained with shell-model wave functions for the 11/2 − state indicates a triaxial shape with deformation parameters β ∼ 0.16 and γ ∼ 20 • [16], which is consistent with the wobbling interpretation. These new results motivate us to investigate the g-factor and SQM as functions of the spin I in the wobbling motion by taking the case of 133 La as the first example.…”

“…Very recently, in Ref. [16] the g-factor and the static (spectroscopic) quadrupole moment (SQM) were measured for the bandhead state (an 11/2 − isomeric state) of the yrast band of 133 La. The obtained g-factor is g = 1.16 ± 0.07 and SQM is |Q| = 1.71 ± 0.34 eb.…”

“…Using this formula, a deformation parameter of β = 0.28 ± 0.10 has been extracted in Ref. [16] under the assumption K = 1/2 from the measured SQM |Q| = 1.71 ± 0.34 eb for the 11/2 − isomeric state at the bandhead of 133 La. In Fig.…”

The g-factor and static quadrupole moment for the wobbling mode in the nuclide 133 La are investigated as functions of the spin I by employing the particle rotor model. The model can reproduce the available experimental data of g-factor and static quadrupole moment. The properties of the g-factor and static quadrupole moment as functions of I are interpreted by analyzing the angular momentum geometry of the collective rotor, proton-particle, and total nuclear system. It is demonstrated that the experimental value of the g-factor at the bandhead of the yrast band leads to the conclusion that the rotor angular momentum is R ≃ 2. Furthermore, the variation of the g-factor with the spin I yields the information that the angular momenta of the proton-particle and total nuclear system are oriented parallel to each other. The negative values of the static quadrupole moment over the entire spin region are caused by an alignment of the total angular momentum mainly along the short axis. Static quadrupole moment differences between the wobbling and yrast band originate from a wobbling excitation with respect to the short axis.

“…The SNV interaction consists of the SNBG3 interaction for the neutron-neutron part, the N82GYM interaction for the proton-proton part, and the monopole-based universal (V MU ) interaction for the neutron-proton part [47]. The SNV interaction has been used to investigate nuclear structure of 133−134 Ba and 133,135 La [48][49][50].…”

The theoretical uncertainty in the nuclear Schiff moment is an obstacle to set constraints on CP violation beyond the standard model from experimental upper bounds on atomic electric dipole moments. We perform large-scale shell-model calculations of the 129 Xe and 199 Hg nuclei with realistic effective interactions. The Schiff moments of 129 Xe and 199 Hg are reduced due to the configuration mixing by ∼ 10% from the evaluation of the independent particle model. On the other hand, the reduction is more significant in mean-field based calculations and shell-model calculations with a drastic truncation. In order to resolve the discrepancy in the Schiff moment of 199 Hg among several nuclear models, we survey low-energy nuclear structure. The large-scale shell-model calculations reveal that the Schiff moment of 199 Hg is considerably quenched in the second 1 2 − state.

“…It should be noted that almost all experiments focus on energy spectra and electromagnetic transition probabilities, while nuclear multipole moments are studied very rarely. The g-factor and static quadrupole moment (SQM) have been measured only for the bandhead state in 133 La [18] and their behavior as a function of spin I were predicted in Ref. [19] employing the particle-rotor model (PRM).…”

$g$-factor and static quadrupole moment of $^{135}$Pr, $^{105}$Pd, and $^{187}$Au in wobbling motion

The g-factor and static quadrupole moment of the nuclides 135 Pr, 105 Pd, and 187 Au in the wobbling motion are investigated in the particle-rotor model as functions of the total spin I. The g-factor of 105 Pd increases with increasing I, due to the negative gyromagnetic ratio of a neutron valenceneutron. This behavior is in contrast to the decreasing g-factor of the other two nuclides, 135 Pr and 187 Au, which feature a valence-proton. The static quadrupole moment Q depends on all three expectation values of the total angular momentum. It is smaller in the yrast band than in the wobbling band for the transverse wobblers 135 Pr and 105 Pd, while larger for the longitudinal wobbler 187 Au.
