被引用回数:3 パーセンタイル:31.66(Physics, Nuclear)An experiment has been performed to study excited states in the neutron-deficient nucleus Ir via the use of the JUROGAM II high-purity germanium detector array and the RITU gas-filled separator at JYFL, Jyvskyl. By using isomer tagging, an isomeric state with a half-life of 6.58(15) s has been observed in Ir for the first time. It has been established that the isomer decays via a 45.2 () - 26.1 () keV cascade to new states below the previously reported ground state in Ir with . We now reassign this state to the isomeric state discovered in this study.
