Abstract:

In order to estimate the fission width for the case in which the Bohr-Wheeler model is inapplicable due to a fission barrier Bf ≃0, we introduce the mean first passage time method and discuss the usefulness of this method. By using this method, the fission decay time can be obtained without solving the Smoluchowski equation, which involves a time consuming calculation. This method is useful when we need to calculate the fission width with a vanishing fission barrier, as when we estimate the fusion evaporation residue cross section for superheavy nuclei with Z > 114.
