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


 The α decay and cluster radioactivity of half-life nuclei are calculated uniformly. The Universal Decay Law(UDL)[C. Qi et al., Phys. Rev. Lett. 103, 072501 (2009)] is reﬁtted to include minimum angular momentum eﬀect and unpaired nucleon eﬀect. The UDL formula and neural network approach to describe α 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 α 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 α decay of superheavy nuclei.
