Wobbling motion in triaxial superdeformed nuclei
We discuss some characteristic features of the wobbling motion excited on the triaxial superdeformed Lu nucleus. We show how these features are connected to the moments of inertia microscopically calculated by means of the quasiparticle RPA in the rotating frame.
متن کاملThe ∆I=4 bifurcation in superdeformed bands
The origin of the ∆I=4 staggering effect which has recently been observed in several su-perdeformed bands is discussed. The Hamamoto and Mottelson model, which is based on a phenomenological parametrization of the hamiltonian as a quartic function of angular momentum , is analyzed. A stability of the description with respect to the C 4-symmetry breaking terms is studied. Recently, a puzzling ne...

متن کاملRotor Model for Rotational Bands of Superdeformed Nuclei
A nonrigid rotor model is developed from the two-parameter quantum algebra U qp (u 2). [This model presents the U qp (u 2) symmetry and shall be referred to as the qp-rotor model.] A ro-tational energy formula as well as a qp-deformation of E2 reduced transition probabilities are derived. The qp-rotor model is applied (through fitting procedures) to twenty rotational bands of superdeformed nucl...
متن کاملCranked Relativistic Mean Field Description of Superdeformed Rotational Bands
The cranked relativistic mean field theory is applied for a detailed investigation of eight superdeformed rotational bands observed in Tb. It is shown that this theory is able to reproduce reasonably well not only the dynamic moments of inertia J (2) of the observed bands but also the alignment properties of the singleparticle orbitals. In the relativistic mean field (RMF) theory the nucleus is...
