A comprehensive level scheme of 93Nb below 2 MeV has been constructed from information obtained with the 93Nb(n,n'γ) and the 94Zr(p,2nγ γ)93Nb reactions. Branching ratios, lifetimes, transition multipolarities, and spin assignments have been determined. From M1 and E2 strengths, fermionic-bosonic excitations of isoscalar and isovector characters have been identified from the weak couplings of the π1g9/292 40Zr and π 2p-11/2Θ94 42Mo configurations. A microscopic interpretation of such excitations is obtained from shell-model calculations, which use low-momentum effective interactions.
