Systematic study of proton radioactivity half-lives based on the relationship between Skyrme-Hartree-Fock and the macroscopic quantities of nuclear matter*

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 MSL0 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.

Automated summary

In this study, the proton radioactivity half-lives of 33 spherical nuclei were systematically investigated based on the correlation between Skyrme parameters and macroscopic quantities of nuclear matter. A new Skyrme parameter set was obtained by fitting the two most weighted macroscopic quantities, and the theoretical proton radioactivity half-lives calculated using this new parameter set showed better agreement with experimental data compared to previous models.
