Abstract

The 253.3 keV isomeric state located in 93Rb was studied at the HRIBF in Oak Ridge. The state in question was populated in the decay of 93Kr produced by proton–induced fission of 238U and separated using the isotope separation on–line technique. We report that the 253.3 keV level does not reveal isomerism and the upper limit of the half–life from our measurement is 4 ns. Our findings are supported by previously reported results that were not taken into account in the latest nuclear databases.
