Abstract

The β-delayed γ decay of ${}^{108}{Nb}$ has been studied using the on-line mass-separator technique. The measured β-decay half-life 0.20±0.03 s agrees with the previous measurement based on β-delayed neutron detection. The lifetime of the first $2^{+}$ state in ${}^{108}{Mo}$ was measured to be 0.5±0.3 ns, which is consistent with a deformation β≊0.4. Spin and parity of $2^{+}$ are suggested for the ground state of ${}^{108}{Nb}$ . © 1996 The American Physical Society.
