Particle decays of levels in 11, 12N and 12O investigated with the invariant-mass method

NUCLEAR REACTIONS 9Be(13O, 12O), (13O, 12N), (13O, 11N), E=69.5 MeV/nucleon, [secondary 13O beam from 9Be(16O, 12O), E=150 MeV/nucleon primary reaction, followed by separation of ion beam using A1900 magnetic separator]; measured charged particles, (particle)(particle)-coin, cross sections using the High Resolution Array (HiRA) of 14 ΔE-E Si-CsI(Tl) telescopes at NSCL, MSU facility. 12,13O, 12N; deduced levels, J, π, 2p-, 3p-, 1p- and 2p+α-decay branches, p+10C, p+11C, 2p+10C invariance mass spectra, widths, total decay energy spectrum and invariant-mass spectra from coincident 4p+2α events. Comparison with Gamow coupled-channel (GCC) calculations, and with previous experimental data in the ENSDF database.
