Alpha Half-Time Estimates for the Superheavy Elements

We present a coupled channel method for calculating the emission rates based on selfconsistent models for nuclear structure and low-energy dynamics. Phenomenological adjustment of model parameters is discussed in detail. The α-decay properties of some new superheavy elements under current experimental research are estimated using the shell model preformation amplitude and resonant reaction amplitudes for open decay channels. Some extensions and applications of the method to resonant particle spectroscopy technique in studies of α-clustering and fine structure with position-sensitive charge particle detectors are discussed.
