Excitation functions are predicted for the production of isotopes of a superheavy nucleus with charge number in the -evaporation channels of the complete fusion reactions Ca+U for future experiments. The calculated production cross section of the Cn isotope in the hot fusion reaction Ca+U is compared with the experimental one in the cold fusion reaction Zn+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 produced in cold and hot fusion reactions is indicated.
