Half-lives of alpha-decay from nuclei with Z=92-118 using the double folding model with relativistic NN interactions

The alpha-decay half-lives of nuclei with Z = 92 - 118 have been calculated using the WKB semi-classical approximation. The a-daughter nuclear interaction potentials are obtained from the double folding model, where the effective nucleon-nucleon (NN) interactions are obtained from relativistic mean field theory Lagrangian (R3Y). In addition to using R3Y NN interactions containing only linear sigma, omega, and rho mesons (R3Y-HS), R3Y parametrizations containing non-linear terms (NL2 and NL-SH) are also employed. In fact, they are found to give better descriptions of the alpha-decay half-lives than R3Y-HS. Moreover, two empirical formulas are employed in the study. They have been included to further test the accuracy of the R3Y models. (C) 2021 Elsevier B.V. All rights reserved.
