Abstract
In the present paper, negative-parity bands based on the $\ensuremath{\nu}{h}_{11/2}$ configuration in $^{125}\mathrm{Xe}$ have been revisited. This nucleus was populated through the reaction $^{82}\mathrm{Se}(^{48}\mathrm{Ca},5n)^{125}\mathrm{Xe}$ at a beam energy of 205 MeV and the corresponding $\ensuremath{\gamma}$ rays were observed using the Gammasphere spectrometer. Evidence for first and second phonon wobbling excitations has been established by measurements of directional correlation ratios and angular distributions of the involved $\ensuremath{\gamma}$ rays. The observed wobbling energy of the bands involved were compared with the recently published results obtained within the framework of triaxial projected shell-model calculations.
