抄録
The γ rays associated with β decay of the 21/2^+ isomer in ^<93>Mo (Ex=2.425 MeV, T_<1/2>=6.85 h) were measured with a selective sensitivity to long-lived isomer decays. A new 1262-keV transition was found in the γ-γ coincidence measurement, and it was attributed to a transition in ^<93>Nb, which is the daughter nucleus of the β decay of the ^<93>Mo isomer, from the 2.753- to the 1.491-MeV levels. Accurate γ-ray intensity balances have determined the β-decay intensity from the ^<93>Mo isomer to the 2.753-MeV level in ^<93>Nb and placed no appreciable intensity for the previously reported β-decay branching to the 2.180-MeV level, for which a recent in-beam γ-ray experiment assigned to be I^π = 17/2^-. Based on the γ-ray intensities from the 2.753-MeV level, spin-parity assignment of this level was revised from 21/2^+ to 19/2^+. The observed β-decay intensity and the spin-parity assignment were explained by the jj-coupling shell model calculations.
