Abstract Theβ − decay of the longer-lived isomer in100Nb has been studied at the fission-product separator JOSEF. Measurements ofγ-ray singles spectra, ofγ-γ coincidences and ofγ-γ angular correlations have been performed. A value oft 1/2=2.99(11)s has been determined for the isomer which probably hasI π=4+ or 5+. A scheme of the levels of100Mo which are populated in the decay of this isomer has been established. Information on the spins of several states of100Mo has been obtained. Thus,I=0 levels have been identified at 1,505, 2,038 and 2,087 keV. The mixing ratios have been determined for the 22 +→21 + and 23 +→21 + transitions. The results provide evidence for a vibrational structure of100Mo with separate bands based on the ground state and on the first excited 0+ level.
