Production of heavy neutron-rich nuclei in transfer reactions within the dinuclear system model

The dynamics of nucleon transfer processes in heavy-ion collisions is investigated within the dinuclear system model. The production cross sections of nuclei in the reactions Xe-136+Pb-208 and U-238+Cm-248 are calculated, and the calculations are in good agreement with the experimental data. The transfer cross sections for the Ni-58+Pb-208 reaction are calculated and compared with the experimental data. We predict the production cross sections of neutron-rich nuclei Eu165-168, Tb169-173, Ho173-178, and Yb181-185 based on the reaction Yb-176+U-238. It can be seen that the production cross sections of the neutron-rich nuclei Eu-165, Tb-169, Ho-173, and Yb-181 are 2.84 mu b, 6.90 mu b, 46.24 mu b, and 53.61 mu b, respectively, which could be synthesized in experiment.
