Odd-even effects in fission induced by heavy ions

About eighty nuclei in the A≈100 mass region have been observed as fission fragments following the fusion evaporation 28,30Si+176Yb at 145 MeV bombarding energy. These nuclei have been identified from their γ-ray cascades detected with the EUROGAM2 array. The level schemes of several stable or neutron-rich nuclei have been extended to higher spins. From coincidences between transitions in complementary fragments, γ-rays de-exciting new high-spin states of hitherto unexplored isotopes can be assigned and some aspects of the fission mechanism can be studied.
