Theoretical progress on production of isotopes in the multinucleon transfer process

As one promising approach for producing nuclei beyond the beta-stability line, the multinucleon transfer (MNT) process has been extensively investigated in past decades. An overview of the theoretical progress on production of isotopes in MNT process is presented. The dinuclear system model, one hybrid approach (GRAZING+DNS model), the improved quantum molecule dynamic model, and the model based on the Langevin equations are summarized. The nucleon transfer mechanisms, such as effects of quasi-elastic and deep inelastic collisions, energy dissipation, N/Z equilibration, and shell structure in collisions of two complex nuclei are discussed. We present the progress on production of the exotic nuclei near the neutron-drip line, the neutron-rich isotopes near N = 126, and the transuranium nuclei.
