The {sup 92-96}Zr nuclei were produced as fission fragments following the fusion reactions {sup 28}Si+{sup 176}Yb and {sup 31}P+{sup 176}Yb at 145 and 152 MeV bombarding energy, respectively. Prompt {gamma} rays emitted in the two reactions were detected with the EUROGAM II and EUROBALL IV arrays. Sequences of {gamma}-ray transitions observed in coincidence were newly assigned to {sup 93-96}Zr. The previously known level schemes have been extended to higher excitation energies and higher spins. The experimental results are discussed in the framework of shell-model calculations with {sup 88}Sr assumed to be an inert core and the valence protons and neutrons filling the {pi}(2p{sub 1/2},1g{sub 9/2}) and {nu}(2d{sub 5/2},3s{sub 1/2}) orbitals.
