Observation of a us isomer in 134-In: Proton-neutron coupling “southeast” of 132-Sn

We report on the observation of a microsecond isomeric state in the single-proton-hole, three-neutron-particlenucleus134In. The nuclei of interest were produced by in-flight fission of a238U beam at the Radioactive IsotopeBeam Factory at RIKEN. The isomer depopulates through a¿ray of energy 56.7(1)...
