Abstract:

The production mechanism of heavy neutron-rich nuclei is investigated by using the multinucleon transfer reactions of 136,148Xe + 208Pb and 238U + 208Pb in the framework of a dinuclear system model. The evaporation residual cross sections of target-like fragments are studied with the reaction system 148Xe + 208Pb at near barrier energies. The results show that the final isotopic production cross sections in the neutron-deficient side are very sensitive to incident energy while it is not sensitive in the neutron-rich side. Comparing the isotopic production cross sections for the reactions of 208Pb bombarded with stable and radioactive projectiles, we find that neutron-rich radioactive beams can significantly increase the production cross sections of heavy neutron-rich nuclei.
