摘要：
The spectroscopy of fission fragments, obtained by the O-18+Pb-208 fusion-fission reaction at 85 MeV bombarding energy, has been performed with the Euroball IV gamma-array. High-spin states in many neutron-rich Se, Br, Kr and Rb of the Ni-78 region nuclei have been identified for the first time. Several physical aspects which govern the nuclear structure in this mass region are underlined thanks to the new results. Among those, empirical values of the residual proton-neutron interactions have been extracted for the pi f(5/2)circle times vd(5/2) and pi p(3/2)circle times vd(5/2) configurations.
