摘要
Our analytical superasymmetric fission (ASAF) model is used to calculate the cluster decay and a decay half-lives of superheavy nuclei with released energies obtained from the experimental and calculated atomic mass tables. Lower values of rms standard deviations of calculated half-lives compared to experimental ones for alpha emitters are produced by the semiempirical (semFIS) formula. The nuclear dynamics based on potential barriers computed by the macroscopic-microscopic method should be improved in the future by replacing the Werner-Wheeler nuclear inertia by the cranking inertia tensor. Up to now spontaneous fission half-lives of the heaviest superheavy nuclei have been estimated only for neutrondeficient nuclei.
