Two-neutron sequential decay of ²⁴O

NUCLEAR REACTIONS ²H(²⁴O, 2n²²O), E=83.4 MeV/nucleon, [²⁴O secondary beam from ⁹Be(⁴⁸Ca, X), E=140 MeV/nucleon primary reaction at NSCL-MSU]; measured charged-particle spectra using position- and energy-sensitive detectors, E(n) and I(n) using MONA-LISA array, three-body decay energy, angular correlations. ²⁴O; deduced level, resonance, l-transfer, width, evidence for two-neutron sequential decay from resonant state. ²³O; deduced intermediate level, J, π through one-neutron decay of ²⁴O resonant state. Comparison with di-neutron and phase-space model calculations for the three-body breakup.
