alpha-Decay half-lives and alpha-capture cross sections are evaluated in the framework of a unified model for alpha-decay and alpha-capture. In this model alpha-decay and alpha-capture are considered as penetration of the alpha-particle through the potential barrier formed by the nuclear, Coulomb, and centrifugal interactions between the alpha-particle and nucleus. The spins and parities of the parent and daughter nuclei as well as the quadrupole and hexadecapole deformations of the daughter nuclei are taken into account for evaluation of the alpha-decay half-lives. The alpha-decay half-lives for 344 nuclei and the alpha-capture cross sections of Ca-40, Ca-44 Co-59, Pb-208, and Bi-209 agree well with the experimental data. The evaluated alpha-decay half-lives within the range of 10(-9) <= T-1/2 <= 10(38) s for 1246 alpha-emitters are tabulated. (C) 2009 Elsevier Inc. All rights reserved.
