【摘要】：Within the framework of the dynamical cluster decay model(DCM), the 1n evaporation cross-sections(σ_(1n)) of cold fusion reactions(Pb and Bi targets) are calculated for ZCN = 104–113 superheavy nuclei. The calculations are carried out in the fixed range of excitation energy E_(CN)~*= 15 ± 1 MeV, so that the comparative analysis of reaction dynamics can be worked out. First of all, the fission barriers(B_f) and neutron separation energies(S_(1n)) are estimated to account the decreasing cross-sections of cold fusion reactions. In addition to this, the importance of hot optimum orientations of β_(2i)-deformed nuclei over cold one is explored at fixed angular momentum and neck-length parameters.The hot optimum orientations support all the target-projectile(t,p) combinations, which are explored experimentally in the cold fusion reactions. Some new target-projectile combinations are also predicted for future exploration. Further,the 1n cross-sections are addressed for Z_(CN) = 104–113 superheavy nuclei at comparable excitation energies which show the decent agrement with experimental data upto Z_(CN) = 109 nuclei. Finally, to understand the dynamics of higher-Z superheavy nuclei, the cross-sections are also calculated at maximum available energies around the Coulomb barrier and the effect of non-sticking moment of inertia(INS) is also investigated at these energies.
