运用推广的液滴模型(GLDM)并结合量子力学中的WKB方法计算了新核素~(263)Hs,~(260)Bh及其α衰变链上各核素的势垒贯穿概率,对该链上各原子核的α衰变半衰期进行了研究.计算结果表明:利用推广的液滴模型结合WKB方法计算出的α衰变半衰期可以很好地符合在超重核区的实验值,验证了推广的液滴模型在超重核区的适用性,能够很好地描述超重核的α衰变.同时,计算表明新核素~(260)Bh和~(263)Hs的合成及其半衰期的测量是可靠的.

The tunneling probability of potential barrier of the newly synthesized superheavy nuclei starting from ~(263)Hs and ~(260)Bh was calculated with the Generalized Liquid Drop Model (GLDM) connected with WKB approximation and their half-lives studied. The calculated results that are in agreement with the experimental data show that the α-decay half-lives of superheavy nuclei with the Generalized Liquid Drop Model connecting with WKB approximation can be successfully, applied in the study of superheavy nuclei and describe the α-decay of superheavy nuclei. The results also indicate that the syntheses of new nuclei ~(260)Bh and ~(263)Hs and the measurements of their α-decay half-lives are reliable.
