Аннотация
The survivability of even-even and odd superheavy nuclei is analyzed on the basis of a statistical model and various theoretical predictions for nuclear properties. In this analysis, use is made of various methods for computing level densities. For Z<114 nuclei, calculations on the basis of all models predicting nuclear properties lead to close values for the ratio of the width with respect to the neutron channel to the width with respect to the fission channel. For Z≥114 nuclei, different values are obtained for this ratio. The dependence of the results on model parameters is discussed. The collective-enhancement factor in the level density is taken into account in the calculations.
