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 ≪ 100 keV) 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. © 2009 Elsevier B.V.
