    Notizen: Abstract Proton radioactivities with decay energies of (0.98±0.08) MeV and (0.83±0.08) MeV were produced by the fusion reactions58Ni+58Ni→116Ba ⋆ and58Ni+54Fe→112Xe ⋆, and their halflives were measured to be (33±7) μs and (109±17) μs, respectively. The intensities of the lines correspond to production cross sections of about 30 μb and 40 μb. The two activities are assigned to the direct proton decay of113Cs and109I. The measured halflives are compared with values calculated ford 5/2 andg 7/2 groundstates of109I and113Cs and spectroscopic factors are deduced for the decays. An extensive search for the proton decay of105Sb, produced in the reaction50Cr(58Ni,p2 n)105Sb, had a negative result, excluding decay energies between 0.5 MeV and 1.5 MeV for halflives between 10 ns and 5 s.

    Excitation-energy sharing in uranium induced dissipative collisions (1990)

    Notizen: Abstract Strongly damped collisions were studied in uranium induced reactions on110Pd and124Sn target nuclei near the barrier. The excitation-energy splitting was deduced from binary reaction yields and those in which the heavy fragment undergoes sequential fission. For systems with 87≦Z≦95 for the heavy fragment, the excitation energy is concentrated in the lighter nucleus, at best shared equally. The results indicate a non-equilibrated energy dissipation, and support nucleon exchange based on average single-particle strength functions as the underlying dissipation mechanism at the barrier.
