**Systematic
calculations
of alpha-decay half-lives of heavy and superheavy nuclei**,

− 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].
