| 英文摘要 | Theoretical estimates for the lifetimes of several isotopes of heavy and superheavy elements with Z = 100-126 are performed in the framework of the generalized liquid drop model including the proximity effects, the mass and charge asymmetry. The alpha-decay half-lives calculated using the experimental Q-values were found to be in reasonable agreement with experimental data. Half-lives with the Q-values from the finite-range droplet model (FRDM) and the macroscopic-microscopic method (MMM) are presented for comparison. It is found that the half-life calculations are quite sensitive to the choice of Q-values. The results show that the half-lives obtained by the theoretical Q-values from MMM are better in agreement with experimental ones than those with Q-values from FRDM. Finally, some predications on the alpha-decay half-lives using the two kinds of theoretical Q-values are provided for future experimental assignment and identification. |
