Multinucleon transfer reactions offer a potential pathway for the synthesis of new neutron-rich isotopes. By using a hybrid model that combines the dinuclear system model and the GRAZING model, the transfer reaction in Kr-86 +(24)8Cm is investigated and found to reproduce experimental results well. Further investigations show that different reactions can selectively produce neutron-rich or neutron-deficient nuclei.
Multinucleon transfer reactions provide a possible access to the synthesis of new neutron-rich isotopes. Within the theoretical framework of a hybrid model combining the dinuclear system model and the GRAZING model together, the transfer reaction is investigated in Kr-86 +(24)8Cm. In this work, it is found that the hybrid model can reproduce experimental transfer cross sections well. After the verification of the hybrid model, the transfer reactions Sn-112,Sn-124,Sn-132 +Cf-249 are investigated by the influence of charge equilibration on the production cross sections of the exotic nuclei. The neutron-deficient projectile Sn-112 shows advantages of producing neutron-deficient nuclei, while Sn-124,Sn-132 are favorable to produce neutron-rich nuclei. In order to obtain available production cross sections of the unknown neutron-rich isotopes with Z = 99-102, the dependence of cross sections on incident energy in the reaction( 132)Sn +Cf-249 is also investigated. It is found that the reaction( 132)Sn + Cf-249 at 510 MeV is a potential candidate to produce unknown neutron-rich isotopes of trans-target.
