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.
