Production cross sections of superheavy nuclei based on dinuclear system model

Theoretical study of the synthesis of superheavy nuclei withZ=119and 120 in heavy-ion reactions with trans-uranium targets

“…the incident energy in the center of mass frame. In this work the capture cross section σ cap is calculated with an empirical coupled channel approach [26,27] and the survival probability W sur is calculated using a statistic model [28,29]. In the fusion process, an excited compound nucleus (CN) may be formed.…”

Production of proton-rich nuclei around Z = 84-90 in fusion-evaporation reactions

“…In this concept, the evaporation residue cross section is expressed as a sum over partial waves with angular momentum J at the center-of-mass energy E c.m. , ) is the penetration probability of the two colliding nuclei overcoming the Coulomb barrier to form the DNS, which is calculated using the empirical coupled channel model [7]. The P CN is the probability that the heavy system evolves from a touching configuration into the formation of compound nucleus in competition with quasi-fission and fission of the heavy fragments [8].…”

“…The structure properties of the proton-rich nuclei (PRN) associated with the fission barrier, density profiles of neutrons and protons, proton-drip line, level spectra etc would be helpful to extend the superheavy region. A number of models have been developed for understanding the formation mechanism of superheavy nuclei and heavy PRN in the fusion-evaporation reactions [7][8][9][10][11][12][13][14][15][16][17][18][19][20]. The formation of superheavy nuclei in the massive fusion reactions is hindered due to the quasifission process.…”

Effects of entrance channel on fusion probability in hot fusion reactions

“…The DNS model has been successfully used in investigating the synthesis mechanism of SHN [20][21][22][23][24][25][26][27][28][29][30][31]. In this work, we focus on the entrance channel effects of P CN in synthesis of SHN within the framework of DNS …”
