  2. 6. Coulomb excitation of 29,30Na
    Michael Seidlitz (Universität zu Köln)
    24/10/2013, 14:05
    Nuclear shell effects in neutron-rich Na nuclei at the border of the island of inversion around N=20 were studied by measuring reduced transition probabilities, i.e. B(E2) and B(M1) values. To this end Coulomb-excitation experiments, employing radioactive 29,30Na beams with a final beam energy of 2.85 MeV/u, were performed at REX-ISOLDE, CERN. De-excitation gamma rays were detected by the...

  3. 5. Coulomb excitation of 26Na with MINIBALL at REX-ISOLDE
    Burkhard Siebeck (Universitaet zu Koeln (DE))
    24/10/2013, 14:30
    Excited states of 26Na were the subject of a Coulomb excitation experiment at REX-ISOLDE employing a radioactive 26Na beam with a final energy of 2.82 MeV/u. De-excitation gamma-rays were detected by the MINIBALL gamma-spectrometer in coincidence with scattered particles in a CD-shaped segmented Si-detector. Reduced transition matrix-elements for the excited states of 26Na at 233 keV and 407...

  13. 2. Quadrupole Collectivity in neutron-rich Cd isotopes
    Sabine Boenig (IKP TU Darmstadt)
    25/10/2013, 09:20
    The neutron-rich cadmium nuclei with a proton number of Z=48 are some of the most interesting isotopes in nuclear structure physics due to the proximity to the proton and neutron shell closures at Z=50 and N=82 respectively. The excitation energy of the 2_1⁺-states shows an irregular behaviour when approaching the neutron shell closure. From 124Cd to 126Cd the energy is only slightly...

  14. 1. Preliminary results from 140Sm Coulomb excitation experiment
    Malin Linnea Klintefjord (University of Oslo (NO))
    25/10/2013, 09:40
    The open-shell nuclei with Z>50 and N<82 are known to have some of the largest ground- state deformations in the nuclear chart. The shape of the nuclei in this region are expected to be prolate, except for a small island of nuclei with Z>62 and N≈78, which are predicted to be oblate. Nuclei near 140Sm are therefore expected to be located in a transitional region between deformed and spherical...

  16. 0. Detection of X rays in the Neutron-Deficient Polonium Coulomb Excitation Experiments
    Nele Kesteloot (Katholieke Universiteit Leuven (BE))
    25/10/2013, 10:50
    Coulomb excitation experiments in inverse kinematics using heavy postaccelerated radioactive ion beams often result in multiple step Coulomb excitation whereby several low-lying excited states are populated. At REX-ISOLDE, the Miniball gamma spectrometer is used for the detection of gamma rays originating from electromagnetic transitions in the investigated nuclei [1]. The nuclear levels...

  17. 4. Coulomb excitation of neutron-deficient radon isotopes
    Dr Liam Paul Gaffney (KU Leuven (BE))
    25/10/2013, 11:10
    The region of proton rich nuclei close to Z=82 is well known for shape coexistence with competition between different spherical, oblate and prolate minima. Data on the light radon nuclei e.g. 198-206Rn is rather limited and largely restricted to information on near-yrast states as inferred from in-beam studies. These studies seem to indicate a change from a largely vibrational behaviour around...
