Abstract : A study of unbound states in 17C by means of one-neutron knockout from a fast moving 18C beam at an energy of 245 MeV/nucleon on a carbon target was performed at the RIKEN-RIBF laboratory utilizing SAMURAI. The energy spectrum of unbound 17C constructed from momentum vectors of the forward going beam velocity 16C fragment and neutron covered an energy range of the decay neutron below about 6 MeV in the center of mass of 17C*. The relative energy Erel spectrum was characterized by two resonances at about 1.92 and 3.24 MeV in Erel and a possible multiplet at around Erel∼0.7 MeV. Momentum distributions of the knockout residue for the Erel = 1.92 and 3.24-MeV states well matched to those of p-wave neutron removal, providing a model independent confirmation of negative parity assignments for these states. The proposed level scheme of 17C was compared with a range of different shell-model predictions; it turned out that the YSOX shell-model interaction, employing the monopole-based universal interaction for the cross-shell two-body matrix elements and incorporating larger ℏ︀ω excitations, gave a consistent account of it, including the locations of the 1/2−1 and 3/2−1 cross-shell states.
