Systematic calculations of alpha-decay half-lives of heavy and superheavy nuclei, Z. Ren, Department of Physics, Nanjing University, China − Alpha decay is a powerful way to identify new nuclides and new elements in heavy and superheavy region.  The different methods to calculate α-decay half-lives and branching ratios are discussed.  Emphasis is placed on the microscopic models of the coupled channel calculations on α-decay branching ratios of heavy nuclei [1-4].  Systematic calculations on the decay-half-lives and branching ratios are carried out by the coupled-channel calculations and good agreement with available data is reached.  This is the systematic calculation on the branching ratios and α-decay half-lives of heavy nuclei.  It is worth noting that the aim is not only to reproduce the experimental data well, but also to extend our understanding of α-decay refined structure [5].
