Heavy-particle radioactivity

The competition of heavy particle radioactivity (HPR) and α decay is investigated in the region of superheavy (SH) nuclei with atomic numbers Z = 104–124. Calculations of half-lives within analytical superasymmetrical fission (ASAF) model are performed by using different theoretical mass tables to d...

Summary:The competition of heavy particle radioactivity (HPR) and α decay is investigated in the region of superheavy (SH) nuclei with atomic numbers Z = 104–124. Calculations of half-lives within analytical superasymmetrical fission (ASAF) model are performed by using different theoretical mass tables to determine Q, the energy released. For α decay the calculations are made using semi-empirical Fission (semFIS) model and AME11 mass table. A trend toward shorter half-lives and larger branching ratios relative to alpha decay for heavier SHs is observed.
