Abstract

A two-neutron unbound excited state of O24 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±0.2MeV with respect to the ground state. Three-body correlations for the decay of O24→O22+2n show clear evidence of a sequential decay through an intermediate state in O23. Neither a di-neutron nor phase-space model for the three-body breakup were able to describe these correlations.
