摘 要: | By using a new five-parameter formula derived from the WKB approximation, we systematically calculate the spontaneous fission half-lives of even-even nuclei with Z=90—108. The isospin effect is taken into account in the new formula. The calculated half-lives agree well with the experimental data. In addition, we predict the spontaneous fission half-lives of superheavy nuclei with Z=108—114. Our predictions may provide references for future experiments.
