Structure of the unbound11Nnucleus by the(3He,6He)reaction

The ground state and low-lying levels of the unbound ${}^{11}\mathrm{N}$ nucleus were investigated with the three-neutron pickup reaction ${}^{14}\mathrm{N}{(}^{3}\mathrm{He}{,}^{6}\mathrm{He}{)}^{11}\mathrm{N}.$ The energies and widths of these, experimentally observed, levels are compared with other measurements and calculations. Angular distributions were measured for the first time for this reaction. The distorted-wave Born approximation analysis confirms the spin assignments for the lowest levels.
