摘要：

Lifetime values for alpha decay in even-even nuclei with Z = 84-98 and N = 128-152 have been calculated in the superasymmetric fission model. The interaction between the alpha particle and the daughter nucleus has been formed in the double folding approach using a density dependent NN interaction. The densities have been obtained using the Relativistic Mean Field formalism. The spectroscopic factors for the decays have been deduced and are shown to vary smoothly as a function of effective numbers of valence nucleons, N-p and N-n chosen with a suitable core. The implication of such a smooth behaviour has been discussed. (C) 2008 Elsevier B.V. All rights reserved.
