  In the present work, we systematically study the proton radioactivity
half-lives of 33 spherical nuclei based on the relationship between the 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 macroscopic quantities
was analyzed. Moreover, we obtained a new Skyrme parameter set by fitting the
two most weighted macroscopic quantities. Compared with Skyrme parameters MSL0
and the theoretical model of proton radioactivity UDLP, the theoretical proton
radioactivity half-life calculated by the new Skyrme parameter set can better
reproduce the experimental data.
