CLUSTER DECAY OF THE HEAVIEST SUPERHEAVY NUCLEI

摘要

The competition of cluster decay (CD) and a decay is investigated in the region of superheavy (SH) nuclei with atomic numbers Z = 104 - 124. Calculations of half-lives within analytical superasymmetric fission (ASAF) model are performed by using the newest AME12 mass table as well as different theoretical mass models to determine the energy released, Q. For a decay the calculations are made using semFIS (semi-empirical Fission) model. A trend toward shorter half-lives and larger branching ratios relative to alpha decay for heavier SHs is observed.
