Abstract
The spontaneous fission half‐lives of heavy and superheavy nuclei from 232Th to 286114 are calculated within the parabolic potential approximation by taking nuclear structure effects into account [Phys. Rev. C 78, 044329 (2008)]. The agreement between theoretical results and the newly observed data is very good in our calculations. The average deviation between data and theory is within a factor of 10 for total 45 spontaneous fission nuclei. This level of agreement is very satisfactory because the spontaneous fission is much more complex than other decay modes such as light cluster radioactivities.
