A comparative analysis of alpha-decay half-lives for even-even Pb-178 to U-234 isotopes

摘要

The feasibility for the alpha decay from the even even transitions of Pb-178 to U-234 isotopes has been studied within the Coulomb and proximity potential model (CPPM). The alpha decay half-lives are considered from different theoretical approaches using Semi-empirical formula of Poenaru et al. (SemFIS), the Universal Decay law (UDL) of Qi et al., Akrawy-Dorin formula of Akrawy and Poenaru (ADF), the Scaling law of Brown (SLB) and the Scaling Law of Horoi et al. (SLH). The numerical results obtained by the CPPM and compared with other method as well the experimental data. (C) 2017 Elsevier B.V. All rights reserved.
