Dr Przemyslaw ADRICH (NSCL)03/04/2008, 09:50Invited PresentationGamma-rays emitted from bound excited states carry valuable information on the structure of the nucleus. At present, in-beam gamma-ray spectroscopy with fast beams combined with a set of robust experimental techniques contributes in many ways to new discoveries and insights into the structure of nuclei far from stability. An overview of in-beam gamma-ray experimental techniques, illustrated...Go to contribution page

Mrs Patricia Roussel-Chomaz (GANIL)03/04/2008, 10:55Collectivities and shell effects in neutron/proton-rich nucleiPresentationWe have studied the spectroscopy of neutron rich nuclei in the region of N=20 with a new method, using different reactions to produce the same nucleus. A composite secondary beam formed by several nuclei in the region of the island of inversion was produced by fragmentation at GANIL with the SISSI device, at an energy close to 30 MeV/nucleon. It was transported to the VAMOS spectrometer beam...Go to contribution page

Mr Megumi NIIKURA (CNS, University of Tokyo)03/04/2008, 11:35Collectivities and shell effects in neutron/proton-rich nucleiPresentationIn nuclei near closed shell, shell structure can be studied by looking at high-spin states. At excited states with certain amount of spins, these nuclei need to promote nucleons across the shell gap in order to gain larger angular momentum. Such core excitation across the N=28 shell gap have been previously discussed in even-even nuclei of N=28 isotones both experimentally and...Go to contribution page

Mr Hiroshi Oba (Graduate School of Science and Technology, Niigata University)03/04/2008, 17:00Exotic deformation / new collective motion at low and high spinPresentationRecent experiments on the neutron rich Cr isotopes with N=36,38 suggest a new region of quadrupole deformation[1][2]. In this presentation we analyse the deformation mechanism in this region by means of a deformed Skyrme-Hartree-Fock-Bogoliubov code based on a 2D mesh representation in the cylindrical coordinate system assuming axial symmetric deformations[3]. It is found that when we adopt...Go to contribution page

Dr Masayuki Yamagami (RIKEN Nishina Center)03/04/2008, 17:20Collectivities and shell effects in neutron/proton-rich nucleiPresentationWe discuss the unique role of pairing correlations for low-lying rotational excitations in neutron rich Be, Mg and Cr isotopes. Appearance of di-neutron correlation due to the neutron skin and continuum effects, and its influence on the moment of inertia are investigated. We also point out the necessity of the isospin density dependence in the pairing effective force; the usual isoscalar...Go to contribution page

Serge Franchoo (IPN Orsay)05/04/2008, 13:50Collectivities and shell effects in neutron/proton-rich nucleiPresentationThe ground state and first excited 2+ state in proton-rich 36Ca have been studied at Ganil by gamma-ray spectroscopy of one-neutron knock-out reactions from deeply bound states in 37Ca at intermediate energy. The 2+ energy in 36Ca was found to be consistent with a sizeable N=16 gap similar to the Z=16 one observed in the mirror nucleus 36S. Partial cross-sections and momentum distributions of...Go to contribution page

Dr Thorsten Kroell (TU Muenchen)05/04/2008, 14:10Collectivities and shell effects in neutron/proton-rich nucleiPresentationExperiments with exotic nuclei are the essential tool to investigate nuclear structure far-off stability. In particular, our research programme focuses on the study of the evolution of magic shell closures. These may change or even (dis)appear globally as function of isospin or locally because of a variation of the residual interactions. An important instrument for our studies...Go to contribution page

Mr Nobuo HINOHARA (Kyoto University)05/04/2008, 14:30Collectivities and shell effects in neutron/proton-rich nucleiPresentationWe have investigated the oblate-prolate shape coexistence/mixing phenomena in proton-rich nuclei around 68Se and 72Kr by means of the adiabatic self-consistent collective coordinate (ASCC) method. For 68Se and 72Kr, it is shown that the collective path extracted from the TDHFB phase space of large dimensions runs approximately along the valley that exists in the triaxially deformed...Go to contribution page
