摘　　要：In this study,we systematically investigate the proton radioactivity half-lives of 33 spherical nuclei based on the relationship between Skyrme parameters and the macroscopic quantities of nuclear matter.Using the two-potential approach with the spherical Skyrme-Hartree-Fock model,the correlation between proton radioactivity half-life and the macroscopic quantities is analyzed.Moreover,we obtain a new Skyrme parameter set by fitting the two most weighted macroscopic quantities.Compared with the Skyrme parameters MSLO and the theoretical model of proton radioactivity UDLP,the theoretical proton radioactivity half-life calculated using the new Skyrme parameter set can better reproduce the experimental data.
