英文摘要: The unfavored alpha transitions of bismuth isotopes, including the newly observed alpha-decay fine structure in Bi-209 [Beeman et al., Phys. Rev. Lett. 108 (2012) 062501] are investigated by the generalized density-dependent cluster model (GDDCM). Instead of the Wentzel-Kramers-Brillouin barrier penetration probability, the exact solution of the Schrodinger equation under outgoing Coulomb wave boundary conditions is presented. The calculated alpha-decay half-lives are found to be in good agreement with the experimental data for both odd-A and odd-odd nuclei. This indicates that the GDDCM has good applicability for unfavored alpha transitions in addition to favored ones. Some predictions on alpha-decay half-lives are also made for reference in future experiments.
