Abstract
The Zr92-96 nuclei were produced as fission fragments following the fusion reactions Si28+Yb176 and P31+Yb176 at 145 and 152 MeV bombarding energy, respectively. Prompt γ rays emitted in the two reactions were detected with the EUROGAM II and EUROBALL IV arrays. Sequences of γ-ray transitions observed in coincidence were newly assigned to Zr93-96. 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 Sr88 assumed to be an inert core and the valence protons and neutrons filling the π(2p1/2,1g9/2) and ν(2d5/2,3s1/2) orbitals.
