  This study employs the dinuclear system model (DNS-sysu) to investigate drift
and fluctuation mechanisms in 136Xe + 209Bi collisions above the Coulomb
barrier. The DNS-sysu model demonstrated its effectiveness in providing
reasonable descriptions of drift and fluctuation dynamics for the multinucleon
transfer reaction at low energies. We observe temperature-induced changes in
the shell effect, impacting nucleon transfer. At higher energies, the weakening
constraint of the potential energy surface leads to a reversal in the evolution
direction. Additionally, the consideration of shell corrections notably affects
fragment distribution at low energies but diminishes for high-energy
conditions. This research provides valuable insights into understanding the
macroscopic manifestation of nucleon transfer in the multinucleon transfer
reaction.
