Alpha decay half-lives calculation of even-even nuclei in the range 62 <= Z <= 118 using Gamow's theory

摘要

The Gamow's theory of alpha decay is used to systematically compute the alpha decay half-lives of even-even isotopes between the atomic numbers Z = 62 and Z = 118. The computation of the alpha decay half-lives of the parent nuclei are done by considering the experimental decay energies (Q) and the penetration frequency (n). These values are compared with experimentally available data and it is found to be in good agreement with the same. The explanation for the obtained patterns of variation of alpha decay half-lives as a function of neutron numbers for the whole region 62 <= Z <= 118 is given by the nuclear shell effect. This computational work proves that the Gamow's theory still holds good for the explanation of the half-lives of alpha emitters. (C) 2019 Elsevier B.V. All rights reserved.
