Dynamical Moments of Inertia And Wobbling Motions In Triaxial Snperdeformed Nuclei
AIP Conference Proceedings, 2005Co-Authors: Masayuki Matsuzaki, Yoshifumi R. Shimizu, Shin-ichi Ohtsubo, Kenichi MatsuyanagiAbstract:We discuss some characteristic features of the wobbling motion excited on the triaxial superdeformed Lu and Hf nuclei. We show these features are determined by the behavior of the Moments of Inertia.

Nuclear Moments of Inertia and wobbling motions in triaxial superdeformed nuclei
Physical Review C, 2004Co-Authors: Masayuki Matsuzaki, Yoshifumi R. Shimizu, Kenichi MatsuyanagiAbstract:The wobbling motion excited on triaxial superdeformed nuclei is studied in terms of the cranked shell model plus random phase approximation. Firstly, by calculating at a low rotational frequency the \gamma-dependence of the three Moments of Inertia associated with the wobbling motion, the mechanism of the appearance of the wobbling motion in positive-\gamma nuclei is clarified theoretically -- the rotational alignment of the \pi i_{13/2} quasiparticle(s) is the essential condition. This indicates that the wobbling motion is a collective motion that is sensitive to the single-particle alignment. Secondly, we prove that the observed unexpected rotational-frequency dependence of the wobbling frequency is an outcome of the rotational-frequency dependent dynamical Moments of Inertia.

dynamical Moments of Inertia associated with wobbling motion in the triaxial superdeformed nucleus
European Physical Journal A, 2003Co-Authors: Masayuki Matsuzaki, Yoshifumi R. Shimizu, Kenichi MatsuyanagiAbstract: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 into account the direct contribution to the Moments of Inertia from the aligned quasiparticle(s) so as to realize \(\mathcal{J}_x > \mathcal{J}_y\) in positive-\(\gamma\) shapes.

K π = 1 + pairing interaction and Moments of Inertia of superdeformed rotational bands in atomic nuclei
Physical review. C Nuclear physics, 1994Co-Authors: I. Hamamoto, Witold NazarewiczAbstract:The effect of the pairing interaction coming from the rotationally induced [ital K][sup [pi]]=1[sup +] pair-density on the nuclear Moments of Inertia is studied. It is pointed out that, contrary to the situation at normal deformations, the inclusion of the [ital K][sup [pi]]=1[sup +] pairing may appreciably modify the frequency dependence of the Moments of Inertia at superdeformed shapes.
