Abstract
A two-neutron unbound excited state of O-24 was populated through a (d, d') reaction at 83.4 MeV/nucleon. A state at E = 715 +/- 110 (stat) +/- 45 (sys) keV with a width of Gamma < 2 MeV was observed above the two-neutron separation energy placing it at 7.65 +/- 0.2 MeV with respect to the ground state. Three-body correlations for the decay of O-24 -> O-22 + 2n show clear evidence of a sequential decay through an intermediate state in O-23. Neither a di-neutron nor phase-space model for the three-body breakup were able to describe these correlations.
