    Abstract

    The ground state of the three-proton emitter Na17 has been identified. Energy correlations between the protons and the O14 residue indicate that its decay is sequential initiated by the emission of a single proton to the ground state of Ne16 followed by simultaneous emission of two protons to the ground state of O14, and the derived total decay energy is 4.45(3) MeV. The angular distribution of the proton from the first step indicates that this emission is d-wave and only consistent with a spin parity of 5/2+. This assignment is consistent with state-of-the-art Gamow shell-model calculations. As the ground state of C17 is 3/2+, the assigned spin parity of its mirror Na17 indicates that the pair presents a new case of ground-state mirror symmetry violation (GMSV). Unlike other GMSV cases, which arise solely from either a Coulomb induced shift or deformation effects, the Na17/C17 case is generated by differences in the many-body correlations.
