英文摘要The stability of superheavy nuclei is mainly determined by the competition between alpha-decay and spontaneous fission. We investigate the half-lives of both alpha-decay and spontaneous fission for the heaviest nuclei with proton numbers up to Z = 121. The agreement between theoretical half-lives and available experimental data is fairly well for the superheavy nuclei. Enhanced stability against spontaneous fission is found for the Z = 119 and Z = 120 isotopic chains, which are of current experimental interests, alpha-Decay is predicted to be the dominating decay mode for the Z = 119 and Z = 120 isotopes with estimated half-lives ranging from microseconds to milliseconds.
