Exotic nuclei produced by heavy-ions induced fission

  • Published:
Acta Physica Hungarica New Series Heavy Ion Physics

Abstract

About thirty nuclei in theA≈100 mass region have been produced as fission fragments following the fusion-evaporation reactions28,30Si+176Yb at 145 MeV bombarding energy. These nuclei have been individually 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 cross coincidences between transitions in complementary fragments, γ-rays de-exciting high-spin states of new isotopes can be identified and some aspects of the fission mechanism can be analyzed.
