Phys. Rev. C 77, 044303 (2008) [8 pages]In-beam γ-ray spectroscopy of the neutron-rich nitrogen isotopes 19-22NReceived 30 May 2007; published 9 April 2008 The structure of 19-22N nuclei was investigated by means of in-beam γ-ray spectroscopic technique using fragmentation reactions of both stable and radioactive beams. Based on particle-γ and particle-γγ coincidence data, level schemes are constructed for the neutron-rich nitrogen nuclei. The experimental results are compared with shell model calculations. The strength of the N=14 and Z=8 shell closures and the weakening of the shell model interaction WBT are discussed. © 2008 The American Physical Society URL:
