84. Fusion Hindrance and Pauli Blocking in 58Ni +64Ni

Oral

We report here on the measurement of deep sub-barrier fusion cross sections for $^{58}$Ni +$^{64}$Ni. In this system the influence of positive Q-value transfer channels on sub-barrier fusion was evidenced in a famous experiment by Beckerman et al. [1]. Subsequent experiments for the two symmetric systems $^{58}$Ni +$^{58}$Ni and $^{64}$Ni +$^{64}$Ni showed that fusion hindrance is clearly...

79. Fusion probability of massive nuclei in reactions leading to heavy composite nuclear systems

Oral

Interaction of massive nuclei shows a considerable reduction in fusion cross sections at the Coulomb barrier according to a comparison of experimental cross sections with the calculated ones obtained using a barrier passing (BP) model. Lowered fusion cross sections are accompanied by a high probability of deep-inelastic and quasi-fission (QF) processes arising on the way to fusion. The...

109. Reactions with Exotic Nuclei at Near- and Sub-barrier Energies

Prof. Chengjian Lin (China Institute of Atomic Energy)

Oral

Reaction with Exotic Nuclei at Near- and Sub-barrier Energies become a hot topic of current interest in nuclear physics. In the talk, I would like to present recent results obtained in the nuclear reaction group of CIAE.
The first topic is on the optical model potentials (OMPs) of exotic nuclear systems. Due to the limitations of intensity and quality of RIBs, it is difficult to extract...

6. Study of fusion mechanisms induced by weakly bound nuclei

Dr Gaolong Zhang (Beihang University)

Oral

The study of fusion reaction for weakly bound nuclei at sub-barrier energies is of large interest, especially those studies of the breakup and transfer effects in weakly bound nuclei. Due to the low breakup threshold, the fusion reactions induced by weakly bound nuclei are complicated processes including complete fusion and incomplete fusion. Also, transfer processes, including the one-neutron...
