英文摘要Systematical calculations on the a decay half-lives of nuclei are carried out in a new cluster model (density-dependent cluster model) where the effective potential between alpha cluster and daughter nucleus is obtained from the double folded integral of the renormalized M3Y nucleon-nucleon interaction with the density distributions of the alpha particle and the daughter nucleus. The model reproduces the experimental half-lives within a factor of 3 for many nuclei. The model also works well for new superheavy elements which are the current interests of nuclear physics and chemistry. This successful description of alpha decay data is due to the correct incorporation of the low-density behavior of the effective nucleon-nucleon interaction in the popular M3Y potential. The effective alpha-core potential of the density-dependent cluster model is analyzed and discussed. (c) 2005 Elsevier B.V. All rights reserved.
