Abstract
The spectroscopy of the unstable and unbound nuclei is investigated via the , d) transfer reaction with a 15.7A MeV beam from the SPIRAL facility. The emitted deuterons were detected by the telescope array MUST. The results are analyzed within the coupled-channels Born approximation framework, and a spectroscopic factor for neutron pickup to the is deduced. This value is consistent with a full p3/2 subshell for . Tentative evidence for the first excited state of is found at E MeV (width MeV). The second one is observed at a position compatible with previous measurements, E MeV. Both are in agreement with previous separate measurements. The reproduction of the first excited state below 1 MeV would be a challenge for the most sophisticated nuclear theories.
