Abstract / Description of output

We have investigated the low-energy states of N-11 by the elastic scattering method in inverse kinematics using a C-10 beam and a (CD2)(n) target. Recoil protons were detected at 16 laboratory angles theta(lab) - 4.6 degrees - 18.9 degrees in a Delta E - E detector system. Using the R-matrix method to analyse the C-10 + p elastic cross sections, we found N-11 to be unbound with respect to proton emission by 1.54 +/- 0.02 MeV with a decay width of 0.83 +/- 0.03. These results are used to calculate the two-proton decay width of the O-12 ground state.
