Two-proton decay of ¹²O and its isobaric analog state in ¹²N

NUCLEAR REACTIONS ⁹Be(¹³O, ¹²O), (¹³O, ¹²N), [¹³O secondary beam from ¹H(¹⁴N, X), E=38 MeV/nucleon primary reaction], E=30.3 MeV/nucleon]; measured excitation energy spectra for p+¹¹C, p+¹²C, 2p+¹⁰C, 2p+¹⁰B events. Two proton decay modes of g.s. of ¹²O and excited states of ¹²O and ¹²N. ¹²O, ¹²N; deduced levels, J, π, widths, IAS of ¹²O g.s. in ¹²N. ¹⁰B; deduced level, IAS in ¹⁰B from 2p decay of IAS in ¹²N. ¹³N; deduced level, J, π.

RADIOACTIVITY ¹²O(2p)[⁹Be(¹³O, ¹²O), E=30.3 MeV/nucleon](2p); measured total excitation energy spectra for decay of g.s. of ¹²O.

ATOMIC MASSES ¹²O, ¹²N; analyzed isobaric multiplet mass equation (IMME) for A=12 quintet; deduced mass excesses using the invariant mass method.
