Abstract
Excitation functions are predicted for the production of isotopes of a superheavy nucleus with charge number \(Z=112\) in the \((2-5)n\)-evaporation channels of the complete fusion reactions \(^{48}\)Ca+\(^{233,235}\)U for future experiments. The calculated production cross section of the \(^{277}\)Cn isotope in the hot fusion reaction \(^{48}\)Ca+\(^{233}\)U is compared with the experimental one in the cold fusion reaction \(^{70}\)Zn+\(^{208}\)Pb. The strong correlation between the fusion probability and asymmetry in the entrance reaction channel is revealed. The possibility of filling the gap between the isotopes of superheavy nuclei with \(Z=112\) produced in cold and hot fusion reactions is indicated.
