| Résumé : |
|
The low-lying level structure of the unbound system $^{16}$B has been investigated via single-proton removal from a 35 MeV/nucleon $^{17}$C beam. The coincident detection of the beam velocity $^{15}$B fragment and neutron allowed the relative energy of the in-flight decay of $^{16}$B to be reconstructed. The resulting spectrum exhibited a narrow peak some 85 keV above threshold. It is argued that this feature corresponds to a very narrow (GAMMA ≪100 keV) resonance, or an unresolved multiplet, with a dominant PI(p3/2)$^{−1=$ ⊗ V(d$^{3}$$_{5/2}$)J=3/2+ PI(p3/2)$^{−1}$ ⊗ V (d$^{2}$$_{5/2, s1/2}$)J=3/2+ configuration which decays by d-wave neutron emission. |
