The high-spin level structures of the {sup 96,97}Nb isotopes have been studied. The isotopes were produced in the fission of the compound systems formed in two heavy-ion-induced reactions, {sup 24}Mg (134.5 MeV) + {sup 173}Yb and {sup 23}Na (129 MeV) + {sup 176}Yb. Gamma-ray spectroscopy was accomplished with the Gammasphere array. High-spin states are observed for the first time in both isotopes with excitation energies up to 5.2 and 6.6 MeV in {sup 96,97}Nb, respectively. The coupling of the odd proton occupying the g{sub 9/2} orbital to the yrast states in the subshell closure nucleus of {sup 96}Zr can account for the first excited states of {sup 97}Nb. A comparison with the first excited states in {sup 95}Zr is also attempted. The addition of a neutron hole in {sup 96}Nb results in a much more fragmented level scheme.
