A two-neutron unbound excited state of ^24O 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 Γ < 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 ^24O → ^22O + 2n show clear evidence for a sequential decay through an intermediate state in ^23O. Neither a di-neutron nor phase-space model for the three-body breakup were able to describe these correlations.
