Low-lying neutron unbound states in ¹²Be

NUCLEAR REACTIONS ⁹Be(¹³B, ¹²Be), E=71 MeV/nucleon, [secondary ¹³B beam from ⁹Be(¹⁸O, X), E=120 MeV/nucleon primary reaction; measured particle and neutron spectra, (¹²Be)n-, (¹¹Be)2n-coin using A1900 fragment separator and MoNA-LISA array for neutron and fragment detection at NSCL-MSU facility. ¹²Be; deduced decay energy, level energy, resonance, L-value, J, π, width, one-neutron decay, no evidence for the 2n-decay channel to ¹⁰Be. Comparison with previous experimental results, and with continuum shell model calculation.
