“…Recently, the quantum diffusion approach [98][99][100][101] has also been used to calculate capture cross sections. This model takes into consideration the influence of fluctuations and dissipation effects on capture cross sections.…”

One of the major motivations for low-energy heavy-ion collision is the synthesis of superheavy nuclei. Based on the following two main aspects, various theoretical and experimental studies have been performed to explore the fusion dynamical process of superheavy nuclei production. The first reason is to elucidate and analyze the synthesis mechanism of superheavy nuclei; the other is to search the favorable incident energy and the best combination of projectile and target to produce new superheavy elements and isotopes of superheavy elements.

“…A large enhancement of sub-barrier fusion cross sections have been experimentally observed in many reaction systems with positive Q-value neutron transfer channels [84][85][86][87][88][89][90]. Many efforts have been made to study the effect of the neutron transfer [84,[91][92][93][94][95][96][97][98][99][100][101]. Until now the role of the PQNT effect is still not very clear.…”

We perform a systematic study of capture excitation functions by using an empirical coupled-channel model. In this model, a barrier distribution is used to take effectively into account the effects of couplings between the relative motion and intrinsic degrees of freedom. The shape of the barrier distribution is of an asymmetric Gaussian form. The effect of neutron transfer channels is also included in the barrier distribution. Based on the interaction potential between the projectile and the target, empirical formulas are proposed to determine the parameters of the barrier distribution.Theoretical estimates for barrier distributions and calculated capture cross sections together with experimental cross sections of 220 reaction systems with 182 Z P Z T 1640 are tabulated. The results show that our empirical formulas work quite well in the energy region around the Coulomb barrier. This model can provide prediction of capture cross sections for the synthesis of superheavy nuclei as well as valuable information on capture and fusion dynamics.

“…[5] where the effect of pairing on single-and multi-nucleon transfer was analyzed. Recently, there is a renewal of interest regarding the transfer in the sub-barrier regime in particular to understand its possible effect as a competing or contributing effect to fusion [10,11]. The understanding of pair transfer in that case is of special interest since it gives some information on how a composite pair of interacting particles might be transferred by tunneling.…”

The effect of pairing on small and large amplitude dynamics is discussed. Pairing correlation is treated in a fully microscopic transport theory using a simplified BCS version of the Time-Dependent Hartree-Fock Bogolyubov (TDHFB) theory. The approach is applied to study the Giant Dipole and Giant Quadrupole Resonance in spherical and/or deformed magnesium isotopes showing very good agreement with QRPA theory. The present framework also provides a consistent approach to describe nuclear reactions around the Coulomb barrier. As an illustration, the influence of pairing correlations on multi-nucleon transfer is studied for reactions at sub-barrier energy.
