摘要
A brief summary of the calculated and experimental ground state-ground state alpha-half-lives of the superheavy nuclei with Z=102-120 is presented. The shell model rate theory is used to calculate alpha-decay half-lives in terms of of the clustering and scattering amplitudes. Special attention is given to the shell structure and the resonance scattering effects in the decay channel. Theoretical results are confronted to data and other relevant estimates. First systematics of alpha-decay properties of SHN was performed by studying the half-life vs. energy correlations in terms of atomic number and mass number. Such a systematics shows that the transitions between even-even nuclei are favored, while all other transitions with odd nucleons are prohibited. The accuracy of theoretical calculations is discussed.
