Abstract
The low-lying level structure of the unbound system 16B has been investigated via single-proton removal from a 35 MeV/nucleon 17C beam. The coincident detection of the beam velocity 15B fragment and neutron allowed the relative energy of the in-flight decay of 16B to be reconstructed. The resulting spectrum exhibited a narrow peak some 85 keV above threshold. It is argued that this feature most probably corresponds to a very narrow (Γ≪100keV) resonance with a dominant π(p3/2)−1⊗ν(d5/23)J=3/2++π(p3/2)−1⊗ν(d5/22,s1/2)J=3/2+ configuration which decays by d-wave neutron emission.
