Abstract: The α decay half-lives of the super-heavy nuclei in the mass region (Z≥104) were calculated by Viola-Seaborg formula with three sets of parameters. The calculated results show that all the three sets of parameters caused rather large deviations from the experimental data. To solve this problem, we have done a parameter fitting in the regions of heavy nuclei and super-heavy nuclei respectively, with the least squares method. With the new sets of parameters, the calculated a decay half-lives are in much better agreement with the experimental data. In particular, the results calculated with the new parameters in the region of super-heavy nuclei are even better.
