Abstract
The structure of neutron-rich light nuclei can be investigated by means of in-beam gamma spectroscopy using both stable and radioactive beams. Two suc h experiments have recently been performed at GANIL. (i) Secondary beams of neutron-rich Ge, Zn and Ni isotopes around N = 40 were produced from the f ragmentation of primary Zn-70 Kr-86 beams, and analyzed by means of the LIS E3 spectrometer. For the transitions between the 0(+) ground state and the first 2(+) state, B(E2) values have been extracted from Coulomb excitation cross-section measurement. Some of the obtained results related to the effe ctiveness of the N = 40 spherical sub-shell closure are discussed. (ii) in- beam gamma-spectroscopy of neutron-rich nuclei around Mg-32 produced by fra gmentation of S-36 have been performed recently Gamma decay of relatively h igh-lying excited states have been measured in a large number of exotic lig ht nuclei. New results obtained in a number of neutron-rich nuclei around N = 20 are presented.
