Effects of finitelightspeed correction for the Coulomb interaction on nuclear binding energies and radii in spherical nuclei
Abstract
The finitelightspeed correction to the Coulomb interaction called the Breit correction is discussed with Skyrme HartreeFock calculations. It is found that the correction to the total energy is about $ 800 \, \mathrm{keV} $ for $ {}^{208} \mathrm{Pb} $, while proton and neutron radii do not change significantly. Effects of the Breit correction are also compared to the correction due to the vacuum polarization. It is shown that the two contributions to the total energy are comparable in light nuclei, but the latter dominates in heavy nuclei. Since the covariant (relativistic) density functional theory often includes effects of magnetic interaction and retardation for electromagnetic interaction, the method presented in this work enables one to make a fair comparison between the nonrelativistic and the relativistic density functional calculations for electromagnetic energies.
