摘要：

Aiming to produce new neutron-rich nuclei at N = 126, the multi-nucleon transfer reactions Xe-136+Ir-194, Pb-208 are investigated by using the GRAZING model and the three-dimensional time-dependent Hartree-Fock (TDHF) approach. Deexcitation processes of the primary fragments are taken into account in both models. Comparison with the experimental data of Xe-136+Pb-208 at E-c.m. = 450 MeV indicates that the isotopic production cross sections around the entrance channel can be well reproduced by both models. The results of GRAZING indicate that Xe-136+Ir-194 is a promising candidate for producing new neutron-rich isotones with N = 126. The limitation of using TDHF to investigate multi-nucleon transfer reactions is also discussed.
