英文摘要Based on the newest experimentally extracted nuclear density distributions for double-magic nucleus Pb-208 (Tarbert et al. in Phys Rev Lett 112:242502, 2014), the sensitivity of alpha-decay half-life to nuclear skin thickness is explored in the vicinity of the shell closure region around Pb-208, i.e., isotopes of Z = 82 and isotones of N = 126. With the two-parameter Fermi (2PF) density distributions and an analytically derived formula, the alpha-decay half-life is found to be closely related to the magnitude of nuclear skin thickness. For alpha decays to the Z = 82 isotopes, the alpha-decay half-life is found to decrease with the increasing neutron skin thickness, while the opposite behavior is found for alpha decays to the N = 126 isotones. Therefore, it could be a possible way to extract the nuclear skin thickness from measured alpha-decay half-lives.
