A comprehensive level scheme of {sup 93}Nb below 2 MeV has been constructed from information obtained with the {sup 93}Nb(n,n{prime}{gamma}) and the {sup 94}Zr(p,2n{gamma}{gamma}){sup 93}Nb 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 {pi}1g{sub 9/2} {circle_times} {sub 40}{sup 92}Zr and {pi}2p{sub 1/2}{sup -1} {circle_times} {sub 42}{sup 94}Mo configurations. A microscopic interpretation of such excitations is obtained from shell-model calculations, which use low-momentum effective interactions.
