Abstract
We have investigated the low-energy states of N11 by the resonant elastic-scattering method in inverse kinematics using a C10 beam and a (CH2)n target at the CYCLONE facility at Louvain-la-Neuve. Recoil protons were detected at laboratory angles θlab=5.2°-18.3° in a ΔE-E detector system. The absolute C10+p elastic cross-section data were analyzed in the R-matrix framework. We found N11 to be unbound with respect to proton emission by 1.54±0.02 MeV, with a decay width of 0.83±0.03 MeV. These results are used to calculate the two-proton decay width of the O12 ground state.
