RECENT RESULTS OF FUSION INDUCED BY NEUTRON-RICH RADIOACTIVE BEAMS STUDIED AT HRIBF

摘要

The reaccelerated fission-fragment beams at HRIBF provide a unique opportunity for studying the mechanisms of fusion involving nuclei with large neutron excess. The fusion excitation functions for neutron-rich radioactive ~(132)Sn incident on ~(40)Ca and ~(58)Ni targets have been measured to explore the role of transfer couplings in sub-barrier fusion enhancement. Evaporation residue cross sections for ~(124,126,127,128)Sn+~(64)Ni were measured to study the dependence of fusion probability on neutron excess.
