A fusion-evaporation experiment has been performed with a SPIRAL 76Kr radioactive beam in order to study the deformation of rare-earth nuclei near the proton drip-line. The experimental setup consisted in the EXOGAM γ-array, coupled to the light-charged particles (LCP) DIAMANT detector and to the VAMOS heavy-ion spectrometer. The difficulties inherent to such measurements are enlightened. The coupling between EXOGAM and DIAMANT has been used to decrease the huge background caused by the radioactivity of the beam. It further permits assigning new γ-ray transitions to specific residual nuclei. A γ-ray belonging to the 130Pm level scheme has thus been observed for the first time. [ABSTRACT FROM AUTHOR]

The preferred production mechanisms used to investigate the region of light nuclei, such as O, Ne and F, have been transfer reactions and, more recently, two-step fragmentation. Multi-nucleon transfer reactions can be an important complementary tool to populate this mass region. Deep-inelastic and multi-nucleon transfer reactions have been largely used to study heavier systems, however no information is yet available regarding the effectiveness of these reaction mechanisms going towards lighter nuclei. In this proceeding we present promising preliminary results from an experiment performed with a radioactive 24Ne beam from SPIRAL facility at GANIL using the VAMOS spectrometer in conjunction with the EXOGAM array. © 2006 American Institute of Physics [ABSTRACT FROM AUTHOR]

The structure of the very neutron-deficient rare-earth nuclei has been investigated in the first experiment with the EXOGAM gamma array coupled to the DIAMANT light charged particle detector using radioactive beam of 76Kr delivered by the SPIRAL facility. Very neutron-deficient Pr, Nd and Pm isotopes have been populated at rather high spin by the reaction 76Kr + 58Ni at a beam energy of 328 MeV. We report here the first results of this experiment. © 2004 American Institute of Physics [ABSTRACT FROM AUTHOR]

During an experiment at Jyväskylä laboratory involving a 27 MeV α beam on a thick 154Sm target, γ-spectroscopy of 156Gd was performed using JUROGAM HPGe multidetector array. We will present here experimental results concerning positive parity bands of this nucleus. Level scheme was enriched with more than ten new transitions as well as a new level in a band observed recently. [ABSTRACT FROM AUTHOR]

An experiment has been performed using a SPIRAL 76Kr radioactive beam at GANIL to investigate rare-earth nuclei near the proton drip-line. The EXOGAM gamma array was coupled with the DIAMANT light charged-particle detector and the VAMOS spectrometer. We report here on the powerful of this setup to extract fusion-evaporation γ-rays from a large beam contamination. © 2006 American Institute of Physics [ABSTRACT FROM AUTHOR]
