AbstractAbstract
[en] Six superdeformed bands have been found in the nucleus 192Tl. For two of the bands, the dynamic moment of inertia J(2) is found to be constant with the rotational frequency ℎω. This result can be understood in terms of Pauli blocking of quasiparticle alignments in intruder orbitals, and represents the first experimental evidence that the alignment of these intruders is responsible for the smooth rise in J(2) seen in other superdeformed nuclei of this mass region.

AbstractAbstract
[en] The authors have investigated the onset of deformation at N ≥ 52 by performing high-spin gamma spectroscopy of 96-98Ru using the 65Cu(36S,pxn) reaction with the Argonne-Notre Dame γ-ray facility. From the coincidence data associated with high multiplicity (k ≥ 8) events, they have established two main band structures in 96-98Ru which extend the previously-known level schemes significantly (up to > 20 ℎ). In 96Ru, one of the newly observed structures consists of five rotation-like E2 transitions and feeds into the known 9(-) state; the other structure bypasses the first one, and based on the observed level-spacings, is tentatively described as vibration-like. A rotational-like structure above a spin of 8 ℎ, along with a parallel vibration-like structure, has been observed in 98Ru as well. The data also contain some evidence for a weak sequence of dipole (presumably M1) transitions in 96Ru. This structure might be similar to the high-K oblate bands recently observed in 119-123I and 198-20Pb. 9 refs., 3 figs

AbstractAbstract
[en] The existence of rotational structures in nuclei bordering on the spherical Z= 50 closed shell has been known for some time. Nevertheless, our understanding of collective effects in this region is remarkably incomplete; for example, before this work little high-spin data existed and there were no lifetime measurements to confirm the collectivity associated with the rotational bands observed in Sb (Z = 51) and Sn (Z = 50) nuclei. Furthermore, the role of the h11/2 orbital was virtually unknown, although it has the highest angular momentum of the orbitals in this mass region and therefore is expected to have the most influence on the properties of high-spin states. In the A ∼ 130 and A ∼ 180 mass regions, where highly deformed intruder bands have been observed, it is the neutron i13/2 orbitals, respectively, which are preferentially lowered in energy by a combination of large deformation and fast rotation In lighter nuclei the h11/2 orbital is expected to appear as an intruder configuration.

AbstractAbstract
[en] The proceedings of the conference/workshop have been published in two volumes. One-page abstracts of all contributed papers are in volume 1. The present volume of proceedings (volume 2) contains the text of most of the invited and contributed talks; by author request , it also contains expanded versions of the abstracts of some papers that were not presented orally. The papers are arranged by session number in the order presented at the conference; the expanded abstracts appear at the end of the sessions to which they pertain

AbstractAbstract
[en] The appearance of alternating patterns in B(M1) strengths in f-p-g shell nuclei is surveyed. The M1 alternations in a sequence of N= 41 isotones, in conjunction with particle-rotor model calculations, is shown to provide information about changing γ deformation. In addition to other odd-A nuclei, several odd-odd nuclei are shown to exhibit alternating B(M1) values and signature inversion. alternations have also been reported in a 4 quasiparticle band in 86Zr, where they have been interpreted in terms of the interacting boson model.

AbstractAbstract
[en] The neutron rich nuclei 61,63Co have been studied using the reactions 16O(48Ca,p2n)61Co at 110 MeV and 18O(48Ca,p2n)63Co at 110 MeV respectively. Discrete lines from the channels of interest were investigated using pre-scaled γ singles, charged-particle-γ, neutron-charged-particle-γ and charged particle-γ-γ data. Decay schemes, with level spins deduced from angular distribution data are presented together with preliminary information on the lifetimes of some higher excitation states. These data represent the first study on the medium to high spin states in these nuclei. (author). 9 refs., 1 tab., 4 figs

AbstractAbstract
[en] The nucleus 163Tm was populated by the reaction 37Cl + 130Te. The gamma rays were detected with the NORDBALL spectrometer. Using a very large data set, it has been possible for the first time to establish the unfavoured signature partner of the πh9/2[541]1/2- configuration high enough in spin to determine the AB neutron crossing frequency. 9 refs., 4 figs

AbstractAbstract
[en] We have studied the in-beam γ-ray spectroscopy of 196Po, which is the first Po isotope to exhibit collective vibrational structure. The onset of collective motion occurs in this isotope because of the large overlap between valence protons in h9/2 and valence neutrons in i13/2 orbitals. (author). 7 refs., 2 tabs., 3 figs
