Proton decay of states in [Formula Presented]

The proton-unbound nucleus [Formula Presented] has been studied via kinematic reconstruction of the emitted proton in coincidence with the residual [Formula Presented] daughter nucleus. Resonances in [Formula Presented] were populated by using a 40 MeV/nucleon radioactive beam of [Formula Presented] to induce the reaction [Formula Presented] followed by the proton decay of [Formula Presented] The decay energy spectrum was constructed from the energies and separation angle of the [Formula Presented] and the proton. In addition to protons from the known [Formula Presented] state, at 2.24 MeV above the proton decay threshold, another peak is seen near 1.45 MeV. This peak could potentially be due to the predicted [Formula Presented] ground state and/or due to the decay of the [Formula Presented] state to the first excited state of [Formula Presented]. © 1998 The American Physical Society.
