Alpha-Decay Half-Lives of Superheavy Nuclei

Half‐lives given by self‐consistent models for the α‐clustering and resonance scattering are calculated and compared with data and empirical estimates. The major influence of the pairing, deformed shell closures and screening corrections is evidenced in the systematics of half‐lives and provides a convenient basis for the interpretation of observed trends of the data and for prediction of new results. The very small widths of α‐resonances observed experimentally in fusion‐evaporation reactions, are interpreted as resonance levels of radioactive products, and such a correlation contributes directly to the study of the nuclear structure on the basis of decay data.
