The ground state and low-lying levels of the unbound 11N nucleus were investigated with the three-neutron pickup reaction 14N(3He,6He)11N. 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.
