Abstract

A discrete superdeformed rotational band has been discovered in [sup 144]Gd following the reaction [sup 100]Mo([sup 48]Ti, 4[ital n])[sup 144]Gd at 221 MeV. The dynamical moment of inertia shows a sharp irregularity at [h bar][omega]=0.45 MeV. The intensity of the [gamma]-ray transitions suggests that the irregularity can be associated with a backbend, which is interpreted in terms of the [ital N]=6 proton band crossing. The experimental results are in good agreement with cranked mean field calculations, which indicate the presence of large shell gaps for both protons and neutrons.

Abstract

Unfavored components of doubly decoupled bands are reported. They can be interpreted as having the pseudospin flipped relative to the orientation in the favored components, i.e., antialigned with respect to the rotation axis. In addition, the differences in consecutive transition energies along the favored and unfavored sequences are strikingly similar among them up to [ital I][sup [pi]]=15[sup +] and 14[sup +], respectively. This feature arises from a cancellation of differences in alignments and moments of inertia.

Abstract

High spin states in the neutron deficient nucleus 109Te have been populated with the 58Ni+54Fe reaction at 220 MeV and investigated through γ-spectroscopy methods at the GASP spectrometer making use of reaction channel selection with the ISIS Si-ball. The level scheme has been extended up to an excitation energy of ≈12.1 MeV. The spins and parities of the observed levels are assigned tentatively supporting the identification of two bands of opposite parity connected by strong dipole transitions inferred to be of E1 character. Octupole correlations in 109Te induced by rotation are suggested as the cause of this effect.

Abstract

A rotational band with 15 transitions has been observed in142Eu in an experiment with the GASP Ge detector array by the110Pd(37Cl,5n) reaction. The average energy spacing between the neighbouring transitions is 60 keV, which is similar to the energy spacings in the superdeformed bands in the mass 140 region. The band has a constant dynamic moment of inertia as suggested by Cranked Shell Model calculations.
