Half-lives of levels in 99Nb and 99Mo
- 1. Kernforschungsanlage Juelich G.m.b.H. (Germany, F.R.). Inst. fuer Kernphysik
Description
The half-lives of the 469-keV level in 99Nb and the 236-keV state in 99Mo have been determined to (0.21 +- 0.06) ns and (0.87 +- 0.15) ns, respectively, from β, γ-delayed concidences. Values of B(E2) = (89 +- 28) e2fm4 and B(M1) = (0.017 +- 0.003)μsub(N)2 are deduced for the 469-keV transition in 99Nb and the 138-keV transition in 99Mo. The result for the E2-transition probability seems to be in accordance with the particle-core coupling interpretation of the low-lying levels in 99Nb if 98Zr is used as the core. The M1 probability for 99Mo agrees with the systematics for ''1-forbidden 1gsub(7/2) → 2dsub(5/2) neutron transitions. (orig.)
