Unified description of α decay and cluster radioactivity using the neural network approach and universal decay law

The alpha decay and cluster radioactivity half-life of nuclei are calculated uniformly. The universal decay law (UDL) (Qi et al 2009 Phys. Rev. Lett. 103 072501) is refitted to include minimum angular momentum effect and unpaired nucleon effect. The UDI, formula and neural network approach to describe a decay and cluster radioactivity half-life calculations were improved. We used the UDL formulas and neural network approach to predict the cluster radioactivity half-life of actinide nuclei and a decay half-life of superheavy nuclei Z = 117-120. We hope to contribute to the discovery of new atomic nucleus cluster radioactivity phenomena and theoretical studies of a decay of super-heavy nuclei.

Automated summary

In this study, the alpha decay and cluster radioactivity half-life of nuclei were uniformly calculated. The universal decay law was refitted to account for the minimum angular momentum effect and unpaired nucleon effect. The UDI, formula, and neural network approach for half-life calculations were improved. The UDL formulas and neural network approach were used to predict the cluster radioactivity half-life of actinide nuclei and the decay half-life of superheavy nuclei Z = 117-120. The research aims to contribute to the discovery of new atomic nucleus cluster radioactivity phenomena and theoretical studies of a decay of super-heavy nuclei.
