چکیده انگلیسی
We present a systematic calculation on α-decay half-lives of medium mass nuclei by the improved version of density-dependent cluster model, in which the nuclear potential between α-particle and daughter nucleus is obtained from the double-folding integral of the renormalized M3Y nucleon-nucleon interaction with the matter density distributions of α-particle and daughter nucleus, and the Coulomb potential is obtained from the double-folding integral of the proton-proton Coulomb interaction with the charge density distributions of α-particle and daughter nucleus. For the favored transitions from nuclear ground states, the theoretical partial half-lives of α-decay are in good agreement with experimental ones. On average, the density-dependent cluster model (DDCM) can reproduce the experimental α-decay half-lives of nuclei with Z=52-80 to within a factor of 3 or better. Therefore DDCM gives reliable and accurate results for favored α-decays in the medium mass region.
