Description

The level structure of several Zr isotopes near A=94 (92,93,94,95Zr) has been studied in the fission of the compound nucleus 197Pb, formed in the 24Mg+173Yb reaction at E(24Mg)=134.5 MeV. Sequences of γ-ray transitions, observed in coincidence with known transitions in the complementary Mo fragments, have been newly assigned to 93,95Zr. The previously known level scheme of 94Zr has been considerably extended to higher excitations, and exhibits structural similarities to the level scheme of 92Zr up to spin 10(ℎ/2π). The level schemes of 93Zr and 95Zr can be generally interpreted as the coupling of a d5/2 neutron to the levels of 92,94Zr and 96Zr, respectively. The observed experimental states are compared with theoretical shell-model calculations
