英文摘要The modified two-potential approach (MTPA) is employed to study the exotic alpha-decay near the closed shells Z = 82 and N = 82, 126 within a deformed version of the cluster model. We perform systematic calculations on favored alpha-decay half-lives from both the ground states (g.s.) and the isomeric states (i.s.) by using the microscopic double-folding potential. The obtained alpha-decay half-lives are found to be in good agreement with the experimental data. This indicates that four types of alpha transitions among ground states and isomeric states (g.s. --> g.s., g.s. --> i.s., i.s. --> g.s., i.s. --> i.s.) are well described in a unified model. In addition, the unfavored alpha transitions in the Bi isotopes are investigated to pursue a further understanding of alpha-decay properties. (C) 2011 Elsevier B.V. All rights reserved.
