| The standard -ray energy calibration source is well known based on the 13.5 y decay of its ground state. However, in addition to this decay also has two relatively long-lived isomeric states: a 9 h state at keV and a 96 min state at keV. Here we report a new measurement of the half-lives of both of these isomeric states. Excited states in were populated following the reaction using a 25 MeV proton beam from the K-150 cyclotron at the Cyclotron Institute of Texas A&M University. Post irradiation, rays from the de-excitation of the long lived isomeric states were measured using the six BGO shielded high-purity germanium (HPGe) clover detectors that are part of the STARLiTeR array. The half-life of the isomer was obtained by measuring the decrease in intensity of the 90 keV ray from the cascade to the ground state. The half-life of this state was measured to be 95.8(4) min ... |
