英文摘要 | The alpha-decay half-lives of (285-289)Fl isotopes and their decay chains are investigated by employing the generalized liquid-drop model (GLDM), the unified fission model, the Royer's analytical formula, and the universal decay law. For the GLDM, we take into account the shell correction. The agreement between the experimental data and the calculations indicates that all the methods we used are successful to reproduce alpha-decay half-lives of (285-289)Fl. For the unknown nuclei, the alpha-decay half-lives have been predicted by inputting alpha-decay energies (Q(alpha)) extracted from the finite-range droplet model and the updated Weizsacker-Skyrme-4 (WS4) model. It is found that the shell correction would enlarge the calculated alpha-decay half-lives in the region from (292)Fl to (298)Fl, where the shell effects are evident. We confirm that N = 184 is the neutron magic number and N = 178 is the submagic number by analyzing the alpha-decay half-lives and the shell correction energies. The competition between alpha-decay and spontaneous fission is discussed in detail and the decay modes of (280-283)Fl and (290-305)Fl have been predicted. Our calculations are in good agreement with the experiments for the decay properties of (284-289)Fl. We also predict (280,286)Fl with both alpha-decay and spontaneous fission. The (280-283,290,297)Fl isotopes are alpha decay, (300-305)Fl undergo spontaneous fission, and (296,298,299)Fl would have both alpha-decay and spontaneous fission. We also predict the decay chains of (280-283,290,291)Fl. |
