We have investigated the low-energy states of N by the elastic scattering method in inverse kinematics using a C beam and a (CD) target. Recoil protons were detected at 16 laboratory angles θ = 4.6° - 18.9° in a ΔE - E detector system. Using the R-matrix method to analyse the C + p elastic cross sections, we found N 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 ground state.
