Improved up to date versions of the known α decay half-lives formulae (Fröman, Wapstra et al., Viola-Seaborg, Hornshøj et al., Taagepera-Nurmia and Keller-Münzel) are obtained by changing the additive parameters in order to have a vanishing mean value of the absolute errors. A new semiempirical relationship is derived on the grounds of the fission theory of alpha decay. It takes into consideration explicitly the dependence on the difference from magicity both of the neutron and proton numbers. allowing us to obtain better agreement with experimental data.
