Exploring the possibility of wobbling motion in Ba129

This is the authors' abstract. We don't add key points for this paper.

The structure of the negative parity bands, based on the νh11/2 orbital, in ¹²⁹Ba 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 ΔI=1 γ 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.
