摘要：

The multinucleon transfer reactions in collisions of Xe-136 + Pt-198 at incident energies E-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.
