“…As a reverse quantum tunneling process with fusion, this Pauli blocking potential has been successfully applied to radioactive -cluster decay in heavy nuclei and superheavy nuclei [31][32][33]. Our preliminary studies demonstrate that this Pauli blocking potential can additionally describe the fusion process of -induced and -nucleus-induced reactions well [34][35][36]. However, our previous method was limited in that the projectile must be an nucleus.…”

“…V P In the literature [34][35][36], it is accepted that there is a nonnegligible Pauli repulsive interaction between two colliding nuclei at a density overlap region in addition to the attractive nuclear interaction and the repulsive Coulomb interaction. When the projectile and target nuclei touch, the Pauli blocking effects become increasingly important owing to this density overlap.…”

In this study, the Pauli blocking potential between two colliding nuclei in the density overlapping region is applied to describe the heavy nuclei fusion process. Inspired by the Pauli blocking effect in the -decay of heavy nuclei, the Pauli blocking potential of single nucleon from the surrounding matter is obtained. In fusion reactions with strong density overlap, the Pauli blocking potential between the projectile and target can be constructed using a single folding model. By considering this potential, the double folding model with a new parameter set is employed to analyze the fusion processes of 95 systems. A wider Coulomb barrier and shallower potential pocket are formed in the inner part of the potential between the two colliding nuclei, compared to that calculated using the Akyüz-Winther potential. The fusion hindrance phenomena at deep sub-barrier energies are described well for fusion systems O + Pb and Ni + Ni.

“…3. The calculated and measured [54] data are represented by black solid lines and solid squares, respectively. By comparing the calculated cross sections based on the improved DNS model+GEMINI++ with measured cross sections, we observe that the calculated TLF distributions of proton pickup and stripping channels correctly describe the magnitude and maxima of the observed production cross sections for a wide range of transfers (from to ).…”

Multinucleon transfer reactions near the Coulomb barrier have been investigated based on the improved dinuclear system (DNS) model, and the deexcitation process of primary fragments are described by statistical model GEMINI++. The production cross sections of $^{40,48}$Ca+$^{124}$Sn and $^{64}$Ni+$^{130}$Te based on the DNS model+GEMINI++ have been calculated and compared with the experimental data. The calculated results have reproduced the experimental data. The cross sections of fusion-evaporation reaction, fragmentation reaction and multinucleon transfer reaction in the $40 \leq Z \leq 60$ region are also given in this paper. The results show that in the $40 \leq Z \leq 60$ region, fusion-evaporation and fragmentation reactions have good results in the relatively proton-rich region, but in the extreme proton-deficient region, the MNT reaction is still promising to synthesize proton-rich nuclei.
