Abstract
Lifetime and g-factor measurements have been made with pulsed beam-γ time-differential techniques using the 89Y(α, 2n)91Nb and 88Sr(α, n)91Zr reactions. A mean lifetime τ = 14.4 ± 0.5 nsec and a g-factor of 1.26 ± 0.04 were obtained for the 13 2- 1985 keV level in 91Nb and τ = 41.9 ± 1.2 nsec and g = 0.70 ± 0.01 were obtained for the 15 2- 2288 keV level in 91Zr. These results are compared to theoretical calculations for (πg 9 2)2(πp 1 2) and (πg 9 2)(πp 1 2)(vd 5 2) configurations in 91Nb and 91Zr, respectively. © 1976.
