“…The calculated results for the cold and hot fusion reactions by using the dinuclear system model match well with the available experimental data [20, 27, 29, 29, 30, 32, 41-43, 46, 47, 49, 51, 116, 117]. The fusion probability and the distribution of the quasifission fragments can be reasonably described based on the dinuclear system model [120][121][122].…”

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.

The mechanism of multinucleon transfer (MNT) reactions for producing neutron-rich heavy nuclei around N = 126 is investigated within two different theoretical frameworks: dinuclear system (DNS) model and isospin-dependent quantum molecular dynamics (IQMD) model. The effects of mass asymmetry relaxation, N/Z equilibration, and shell closures on production cross sections of neutron-rich heavy nuclei are investigated. For the first time, the advantages for producing neutron-rich heavy nuclei around N = 126 are found in MNT reactions based on 238 U target. We propose the MNT reactions with 238 U target for producing unknown neutron-rich heavy nuclei around N = 126 in the future.

“…Recently, a renew interest, the damped collisions of two heavy nuclei were investigated and motivated for producing heavy isotopes, in particular for new nuclides close to proton and neutron-rich drip lines. The DNS model can nicely reproduce the production cross sections of fusion-evaporation products and MNT yields [45][46][47][48][49][50][51]. The fragment yields in the MNT reactions are related to the emission angle in the laboratory system.…”

Within the dinuclear system model, unknown neutron-deficient isotopes Np, Pu, Am, Cm, Bk, Cf, Es, Fm are investigated in 40 Ca, 36,40 Ar, 32 S, 28 Si, 24 Mg induced fusion-evaporation reactions and multinucleon transfer reactions with radioactive beams 59 Cu, 69 As, 90 Nb, 91 Tc, 94 Rh, 105,110 Sn, 118 Xe induced with 238 U near Coulomb barrier energies. The production cross sections of compound nuclei in the fusion-evaporation reactions and fragments yields in the multinucleon transfer reactions are calculated within the model. A statistical approach is used to evaluate the survival probability of excited nuclei via the both reaction mechanisms. A dynamical deformation is implemented into the model in the dissipation process. It is found that charge particle channels (alpha and proton) dominate in the decay process of proton-rich nuclides and the fusion-evaporation reactions are favorable to produce the new neutron-deficient actinide isotopes. The total kinetic energies and angular spectra of primary fragments are strongly dependent on colliding orientations.
