Exploring the possibility of wobbling motion in ${}_{129}\mathrm{Ba}$

The structure of the negative parity bands, based on the $\nu h_{11/2}$ orbital, in ${}_{129}\mathrm{Ba}$ is revisited to search for the wobbling mode in this nucleus. Existing angular distribution/correlation and linear polarization results are indicative of a large $E2$ admixture in the 365 keV interconnecting $\Delta I=1$ $\gamma$ transition between yrast bands. This provides an indication of the existence of a wobbling mode in this nucleus. Theoretical calculations performed in this work using the quasiparticle plus triaxial rotor model have effectively replicated the available experimental results.
