Abstract: The possibility of observing wobbling mode in the even-even systems of $^{76}\mathrm{Ge}, ^{112}\mathrm{Ru}, ^{188,192}\mathrm{Os}, ^{192}\mathrm{Pt}$, and $^{232}\mathrm{Th}$ is explored using the triaxial projected shell model approach. These nuclei are known to have $\ensuremath{\gamma}$ bands whose odd-spin members are lower than the average of the neighboring even-spin states. It is shown through a detailed analysis of the excitation energies and the electromagnetic transition probabilities that the observed band structures in these nuclei except for $^{232}\mathrm{Th}$ can be characterized as originating from the wobbling motion. It is further demonstrated that quasiparticle alignment is responsible for driving the systems to the wobbling mode.
