How Rare Is Cluster Decay of Superheavy Nuclei

摘要: Superheavy nuclei produced until now are decaying by \(\alpha \) emission and spontaneous fission (SF). For atomic numbers larger than 121 cluster decay (CD) has a good chance to compete. While the majority of calculated (\(\alpha \)D) half-lives in agreement with experimental data within one order magnitude CD also very well accounted for, discrepancy between theory experiment can be as high ten orders for SF. Further improvement accuracy comes from finding optimal parameters our models: analytical superasymmetric model, universal curve semiempirical formula. SF we study nuclear dynamics based on potential barriers computed macroscopic-microscopic method employing various inertia variation laws. Applications illustrated \(^{284}\)Cn even-even \(Z=118-124\) parent nuclei.
