An improved semi-empirical formula for cluster radioactivity half-lives is proposed by incorporating the influences of reduced mass, the blocking effect of unpaired nucleons and mass asymmetry on the basis of the original Tavares formula [Eur. Phys. J. A 49 (2013) 6]. Using this improved semi-empirical formula, the calculated results of the cluster radioactivity half-lives for the daughter nuclei around 208Pb or its neighbors can reproduce the experimental data well with a corresponding root-mean-square deviation sigma= 0.570, which proves the feasibility of this formula to calculate cluster r...
