Production of new neutron-rich heavy nuclei with $Z=56-80$ in the multinucleon transfer reactions of ${}^{136}$Xe+${}^{198}$Pt

Abstract

The multinucleon transfer reactions in collisions of ${}^{136}$Xe+${}^{198}$Pt at incident energies $E_{\text{lab}}=$5.25, 6.20, 7.98, 10.0, and 15.0 MeV/nucleon are investigated by using the improved quantum molecular dynamics model. It is found that 6.20 MeV/nucleon is the optimal incident energy for producing the neutron-rich heavy nuclei. About 80 unknown neutron-rich nuclei might be produced in this reaction with cross sections from 10${}^{-6}$ to 10${}^{-2}$ mb. The angular distributions of the neutron-rich isotopes are predicted.
