【 摘 要 】

The neutron decay of the resonant states of light neutron-rich nuclei is an important and poorly explored property, useful to extract valuable nuclear structure information. The neutron decay of the15C resonances populated via the two-neutron transfer reaction13C(18O,16O n) at 84 MeV incident energy is studied using an innovative technique which couples the MAGNEX magnetic spectrometer and the EDEN neutron detector array. The data show that the recently observed15C Giant Pairing Vibration at 13.7 MeV mainly decays via two-neutron emission.
