“…In the case of 127 Pr the change of J (2) with rotational frequency coincides with the experimental data, with the observed value athω ≈ 0.4 MeV. However, deviations of the theoretical J (2) from the data are seen at the highest spin states. For 129 Pr, the PSM reproduces very well the experimental data (see Fig.…”

“…Nevertheless, the change of J (2) for 125 Pr is predicted to occur athω ≈ 0.5 MeV while experimentally it occurs at hω ≈ 0.4 MeV, which still can be considered as a good agreement with experiment. In the case of 127 Pr the change of J (2) with rotational frequency coincides with the experimental data, with the observed value athω ≈ 0.4 MeV. However, deviations of the theoretical J (2) from the data are seen at the highest spin states.…”

“…1, we compare the PSM results with experimental data for the 125−133 Pr isotopes. We plot the dynamical moment of inertia J (2) as a function of the rotational frequencyhω and twice the kinetic moment of inertia J (1) as a function ofh 2 ω 2 . These quantities are defined as…”

“…In a number of nuclei, strong deforming shell effects lead to an excited minimum associated with large, prolate deformation (with a major to minor axis ratio of 2:1) [1,2]. The properties of the excitations occurring in this superdeformed (SD) minimum continue to be a subject of much interest.…”

Abstract. Both the quasi-continuum of γ rays as well as the ridges from the feeding (and decay) of superdeformed and normal bands have been extracted in the nucleus 152 Dy. A model has been developed that simultaneously describes all these spectra as well as the feeding intensity of the superdeformed bands. Through the calculation of the continuum of γ rays at finite temperature, the rotational damping width in the normal and superdeformed wells are extracted. This is the first time the rotational damping width in a superdeformed well has been measured in the A 150 mass region.

“…Much attention has been paid to the recent discovery of superdeformed bands in the rare earths --bands that originate from a second prolate minimum in the potential-energy surface of the nucleus (at larger deformation). So (\ far, such bands have been observed in two different regions; a discrete band with 6=0.6 was reported [1] in 152Dy, and a band with 6=0.4-0.5 was found [2][3][4] in 132Ce and in 135Nd. Furthermore, unresolved features (ridges)…”
