英文摘要	In order to produce more unknown neutron-rich nuclei around N = 126, the transfer reactions Xe-136 + Pt-198, Xe136-144 + Pb-208, and Sn-132 + Pb-208 are investigated within the framework of the dinuclear system (DNS) model. The influence of neutron excess of projectile on production cross sections of target-like products is studied through the reactions Xe-136,Xe-144 + Pb-208. We find that the radioactive projectile Xe-144 with much larger neutron excess is favorable to produce neutron-rich nuclei with charge number less than the target rather than produce transtarget nuclei. The incident energy dependence of yield distributions of fragments in the reaction Sn-132 + Pb-208 are also studied. The production cross sections of neutron-rich nuclei with Z = 72-77are predicted in the reactions Xe136-144 + Pb-208 and Sn-132 + Pb-208. It is noticed that the production cross sections of unknown neutron-rich nuclei in the reaction Xe-144 + Pb-208 are at least two orders of magnitude larger than those in the reaction Xe-136 + Pb-208. The radioactive beam induced transfer reactions Xe-139,Xe-144 + Pb-208, considering beam intensities proposed in SPIRAL2 (Production System of Radioactive Ion and Acceleration On-Line) project as well, for production of neutron-rich nuclei around the N = 126 shell closure are investigated for the first time. It is found that, in comparison to the stable beam Xe-136, the radioactive beam Xe-144 shows great advantages for producing neutron-rich nuclei with N = 126 and the advantages get more obvious for producing nuclei with less charge number.
