Abstract

The development of advanced gamma-ray tracking arrays allows for a sensitive new technique to investigate elusive states of exotic nuclei with fast rare-isotope beams. By taking advantage of the excellent energy and position resolution of the Gamma-Ray Energy Tracking In-beam Nuclear Array, we developed a novel technique to identify in-flight isomeric decays of the 0(2)(+) state in Mg-32 populated in a two-proton removal reaction. We confirm the 0(2)(+) -> 2(1)(+) gamma-ray transition of Mg-32 and constrain the 0(2)(+) decay lifetime, suggesting a large collectivity. The small partial cross section populating the 0(2)(+) state in this reaction provides experimental evidence for the reduced occupancy of the normal configuration of the 0(2)(+) state, indicating the intruder dominance of this state.
