论文摘要
质子放射性是富含质子核的自然放射性的重要且常见的过程。在我们以前的工作中[J。 H. Cheng等,Nucl。 Rhys。 A 997,121717(2020)],我们系统地研究了质子放射性的半衰期,其中有53 <z <83核在两势方法中使用了Skyrme-Hartree-fock。计算可以很好地再现球形核的实验数据。目前的工作是先前工作的扩展。我们系统地研究了32个质子放射性的球形核的半衰期,并在115种不同版本的天际相互作用中使用Skyrme-Hartree-fock(TPA-SHF)进行两功能方法。计算结果表明,SLY7 Skyrme相互作用的R.M.S.在所有不同版本的Skyrme相互作用中,球形质子发射器的实验数据描述中的偏差。此外,我们将此模型与SLY7 Skyrme相互作用一起使用,以预测同一区域中7个球形核的质子放射性半衰期,该区域的质子放射性被能量允许或观察到但尚未量化。
Proton radioactivity is an important and common process of the natural radioactivity of proton-rich nuclei. In our previous work [J. H. Cheng et al., Nucl. Rhys. A 997, 121717 (2020)], we systematically studied the proton radioactivity half-lives of 53< Z <83 nuclei within the two-potential approach with Skyrme-Hartree-Fock. The calculations can well reproduce the experimental data of spherical nuclei. The present work is an extension of the previous work. We systematically study 32 proton radioactivity half-lives of spherical nuclei with the two-potential approach with Skyrme-Hartree-Fock (TPA-SHF) within 115 different versions of the Skyrme interactions. The calculated results indicate that the SLy7 Skyrme interaction gives the lowest r.m.s. deviation in the description of the experimental data of the spherical proton emitters among all the different versions of the Skyrme interactions. In addition, we use this model with the SLy7 Skyrme interaction to predict the proton radioactivity half-lives of 7 spherical nuclei in the same region, whose proton radioactivity is energetically allowed or has been observed but is not yet quantified.
