Schiff Screening of Relativistic Nucleon Electric-Dipole Moments by Electrons
arXiv:0705.1981 · doi:10.1103/PhysRevC.76.028501
Abstract
We show, at leading-order in the multipole expansion of the electron-nucleus interaction, that nucleon electric-dipole moments are completely shielded by electrons so that they contribute nothing to atomic electric-dipole moments, even when relativity in the nucleus is taken into account. It is well known that relativistic electron motion, by contrast, leads to dipole moments that are not screened; we discuss the reasons for the difference.
