Abstract
The even- and odd-spin two-quasiparticle yrast bands in $^{136}\mathrm{Nd}$ are investigated with the triaxial projected shell model, focusing on the possible interpretation as transverse wobbling. With the experimental observables reproduced reasonably, the conditions under which the wobbling approximation is valid are examined via the angular momentum geometry and the configuration components extracted from the microscopic wave functions. The impact of the rotational alignment of the quasiparticles on the scenario of transverse wobbling is emphasized. It turns out that the $n=0$ band of the wobbling candidate is more affected than the $n=1$ one, which tends to go against the decreasing trend of the wobbling energy expected in the transverse case.
