Survival probabilities of superheavy nuclei based on recent predictions of nuclear properties

By using the statistical model and recent theoretical predictions of nuclear properties, survival probabilities of superheavy nuclei with respect to the xn evaporation channel (x=1-4) are calculated. Level densities of the Fermi-gas model and of a model with collective enhancement are used. The survival probabilities and the fusion cross-sections calculated within the dinuclear system model are applied to obtain excitation functions of No isotopes in the reactions 48Ca+204,206,208Pb and production cross-sections of superheavy nuclei with Z>102 in cold and hot fusion reactions. The results are in a good agreement with available experimental data. (orig.)
