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

Abstract

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 ${}^{136}$Xe+${}^{208}$Pb and ${}^{238}$U+${}^{248}$Cm are calculated and the calculations are in good agreement with the experimental data. The transfer cross sections for the ${}^{58}$Ni+${}^{208}$Pb reaction are calculated and compared with the experimental data. We predict the production cross sections of neutron-rich nuclei ${}^{165-168}$Eu, ${}^{169-173}$Tb, ${}^{173-178}$Ho, and ${}^{181-185}$Yb based on the reaction ${}^{176}$Yb+${}^{238}$U. It can be seen that the production cross sections of the neutron-rich nuclei ${}^{165}$Eu, ${}^{169}$Tb, ${}^{173}$Ho, and ${}^{181}$Yb 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.
