论文摘要
核子有限大小的电磁效应是在Skyrme Hartree-fock计算的基础上自兼而有的，其中考虑了质子和中子的电代码。此外，考虑了真空极化和电磁自旋轨道相互作用。自一致的有限尺寸效果给常规中子带来了不同的库仑潜力，并影响中子。有限尺寸效果对总能量的贡献达到$ 7 \，\ Mathrm {Mev} $中的$ {}^{208} \ Mathrm {pb} $。真空极化和电磁自旋轨道相互作用也不可忽略，尤其是在重核中。这些效应提供了总能量对核相互作用的异种对称性术语的贡献。还研究了$ {}^{48} \ mathrm {ca} $ - $ {}^{48} \ Mathrm {ni} $中的镜子核质量差异，其值大约提高了一个级级。
The electromagnetic effects of the finite size of the nucleon are implemented self-consistently on top of the Skyrme Hartree-Fock calculation, where the electric form factors of both protons and neutrons are considered. Furthermore, the vacuum polarization and the electromagnetic spin-orbit interaction are taken into account. The self-consistent finite-size effects give a different Coulomb potential from the conventional one and affect the neutrons as well. The contribution of the finite-size effects to the total energy reaches $ 7 \, \mathrm{MeV} $ in $ {}^{208} \mathrm{Pb} $. The vacuum polarization and the electromagnetic spin-orbit interaction are also non-negligible, especially in the heavy nuclei. These effects provide a comparable contribution of the total energy to that of the isospin symmetry-breaking terms of the nuclear interaction. The mirror nuclei mass difference in $ {}^{48} \mathrm{Ca} $--$ {}^{48} \mathrm{Ni} $ is also studied, and its value is improved by approximately one order of magnitude.
