摘要：
The heaviest nuclei produced until now are few isotopes of the oganesson (atomic number Z = 118). We performed calculations of alpha-decay half-lives using the models AKRA (Akrawy, 2017), ASAF (Analytical Super-Asymmetric Fission, 1980), UNIV (Universal Formula, 2006), and semFIS (Semi-empirical formula based on Fission Theory, 1983). Cluster radioactivity half-lives are calculated with ASAF and UNIV models. The most important result of our calculations shows that( 92)(,94)Sr cluster radioactivity of( 303),(304)120 has a branching ratio relative to alpha-decay of -0.10 and 0.49, respectively. We hope that future measurements will prove that cluster decay may compete with alpha decay. Copyright (C) EPLA, 2018
