    The α-decay half-lives of nuclei with Z = 92 − 118 have been calculated using the WKB semi-classical approximation. The α-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 La- grangian (R3Y). In addition to using R3Y NN interactions containing only linear σ , ω, and ρ 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 α-decay half-lives than R3Y-HS. Moreover, two em- pirical formulas are employed in the study. They have been included to further test the accuracy of the R3Y models.
