Dynamical moments of inertia associated with wobbling motion in the triaxial superdeformed nucleus

The three moments of inertia associated with the wobbling mode built on the triaxial superdeformed states in the Lu-Hf region are investigated by means of the cranked shell model plus random-phase approximation to the configurations with aligned quasiparticle(s). The result indicates that it is crucial to take int, o into account the direct contribution to the the moments of inertia from the aligned quasiparticle(s) so as to realize script J signx > script J signy in positive-γ shapes.
