Abstract

A comprehensive level scheme of ${}^{93}{Nb}$ below 2 MeV has been constructed from information obtained with the ${}^{93}{Nb}$ ( $n, n^{'} γ$ ) and the ${}^{94}{Zr}$ ( $p, 2 n γ γ$ ) ${}^{93}{Nb}$ reactions. Branching ratios, lifetimes, transition multipolarities, and spin assignments have been determined. From $M 1$ and $E 2$ strengths, fermionic-bosonic excitations of isoscalar and isovector characters have been identified from the weak couplings of the $π 1 g_{9 / 2} \otimes_{40}^{92} Zr$ and $π 2 p_{1 / 2}^{- 1} \otimes_{42}^{94} Mo$ configurations. A microscopic interpretation of such excitations is obtained from shell-model calculations, which use low-momentum effective interactions.
