Abstract: New recent experimental $\alpha$ decay half-lives have been compared with theresults obtained from previously proposed formulas depending only on the massand charge numbers of the $\alpha$ emitter and the Q$\alpha$ value. For theheaviest nuclei they are also compared with calculations using theDensity-Dependent M3Y DDM3Y effective interaction and theViola-Seaborg-Sobiczewski VSS formulas. The correct agreement allows us tomake predictions for the $\alpha$ decay half-lives of other still unknownsuperheavy nuclei from these analytic formulas using the extrapolated Q$\alpha$of G. Audi, A. H. Wapstra, and C. Thibault Nucl. Phys. A729, 337 2003.
