Abstract
A two-neutron unbound excited state of O was populated through a (d,d') reaction at 83.4 MeV/nucleon. A state at (stat) (sys) keV with a width of 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 O + show clear evidence for a sequential decay through an intermediate state in O. Neither a di-neutron nor phase-space model for the three-body breakup were able to describe these correlations.
