Spectroscopy of the Unbound States of the Drip-Line Nucleus 24O

Abstract : The drip-line 24O nucleus combines several properties which are challenging our understanding of the nuclear structure: it has no bound excited state, and is expected as a neutron-skin nucleus with low-lying resonances. It presents a new shell gap effect at N = 16. To investigate the neutron excitations and the characteristics of this gap, the proton elastic and inelastic scattering by 24O were measured, using the light charged particle spectroscopy technique; the excitation energies of the unbound states were deduced via missing mass method. The experiment was carried out at the RIBF facility in the BigRIPS line, combining the unique intensities of the 24O beam with the state-of-the-art Si-telescope array MUST2. The analysis and the preliminary results are discussed.
