AbstractA new version of the generalized density-dependent cluster model (GDDCM) is developed to describe an alpha particle tunneling through a deformed potential barrier. The microscopic deformed potential is numerically constructed in the double-folding model using the multipole expansion method. The decay width of an alpha-cluster state is evaluated using the integral of the quasi-bound state wave function, the scattering state wave function, and the difference of potentials. We perform a systematic calculation of alpha-decay half-lives for favored transitions in even-even nuclei ranging from Z=52 to Z=104. The calculated half-lives are in good agreement with the experimental values. The relation between nuclear deformations and alpha-decay half-lives is also discussed in details.
