The three-body decay O12→2p+C10 was studied following production via single-neutron stripping from a radioactive O13 projectile. This is the first observation of two-proton emission from an unbound ground state where the one-proton emission channel is energetically closed beyond the lightest case of Be6. No evidence for He2 emission is seen, despite predictions for a large diproton branching ratio. An upper limit of 7% (95% C.L.) is established for this decay branch. The implications of the small diproton branching ratio observed here and seen previously in Be6 are discussed. © 1995 The American Physical Society.
