Abstract

The low-spin structure of Nb93 has been studied using the Nb93(I ,I '), Nb93(n,n'I ) and Zr94(p,2nI I )Nb93 reactions. Lifetimes were determined from both Nb93(I ,I ') and Nb93(n,n'I ) measurements. Branching ratios were measured, and multipolarities and spin assignments were determined from the Zr94(p,2nI I )Nb93 angular correlation experiment. From M1 and E2 strengths, the JÏ€=9/2+ and 7/2+ states at 1297.1 keV and 1483.6 keV, respectively, are proposed as members of the quintet of mixed-symmetry states associated with the Ï€1g9/2a (21,MS+,Zr92) configuration. The large B(M1) values determined in Nb93 cannot be explained within the weak coupling limit of the interacting boson fermion model.
