Production of light neutron-rich nuclei in multinucleon transfer reactions

In order to produce more unknown light neutron-rich nuclei, multinucleon transfer processes at energies slightly above the Coulomb barrier are investigated within the inclusion of the deformations of interacting nuclei as independent variables of the dinuclear system (DNS) model (improved DNS model). Transfer Ni-58,Ni-64+(208)pb and Ca-40+Pb-208 calculated and compared with the experimental data, we find the improved dinuclear system model describes the transfer cross sections reasonably. The calculated results showed that protons and neutrons are transferred to be strongly influenced by the potential energy surface, the injection point position of the projectile on the potential energy surface and the dynamical properties of the DNS. The cross sections of new neutron-rich isotopes through the transfer reactions Ni-70+Pb-208 and S-32,S-36+U-238 are estimated by the multinucleon transfer reactions. (C) 2019 Elsevier B.V.
