摘要：

A systematic calculation of a decay half-lives is presented for even-even nuclei between Te and Z = 118 isotopes. The potential energy governing a decay has been determined within a liquid drop model including proximity effects between the alpha particle and the daughter nucleus and taking into account the experimental Q value. The alpha decay half-lives have been deduced from the WKB barrier penetration probability. The alpha decay half-lives obtained agree reasonably well with the experimental data. (C) 2013 Elsevier B.V.
