Multinucleon transfer dynamics in nearly symmetric nuclear reactions

Within the framework of the dinuclear system model, the multinucleon transfer dynamics for nearly symmetric nuclear collisions has been investigated. The reaction mechanism in the systems of $$^{198}\hbox {Pt}+^{198}\hbox {Pt}$$ and $$^{204}\hbox {Hg}+^{198}\hbox {Pt}$$ was investigated at beam energies around the Coulomb barrier. It was found that the isotopic yields are enhanced with increased incident energy in the domain of proton-rich nuclides. However, the production on the neutron-rich side weakly depends on the energy. The angular distribution with the beam energy was also analyzed in the multinucleon transfer reactions. Projectile-like fragments were produced toward the forward emission with increasing incident energy. The target-like fragments manifested the opposite trend in the transfer reactions.
