Fully self-consistent calculations of nuclear Schiff moments
Shufang Ban, Jacek Dobaczewski, Jonathan Engel, A. Shukla
TL;DR
This paper presents fully self-consistent calculations of nuclear Schiff moments for 199Hg and 211Ra, incorporating shape deformation and CP-violating interactions, revealing significant differences from previous models especially for 199Hg.
Contribution
It introduces a novel self-consistent mean-field approach that includes arbitrary shape deformation and nucleon dipole moments in Schiff moment calculations.
Findings
Results for 199Hg differ significantly from previous models with isovector CP-violating interactions.
Inclusion of shape deformation impacts the calculated Schiff moments.
The method provides a more comprehensive understanding of nuclear CP violation effects.
Abstract
We calculate the Schiff moments of the nuclei 199Hg and 211Ra in completely self-consistent odd-nucleus mean-field theory by modifying the Hartree-Fock-Bogoliubov code HFODD. We allow for arbitrary shape deformation, and include the effects of nucleon dipole moments alongside those of a CP-violating pion-exchange nucleon-nucleon interaction. The results for 199Hg differ significantly from those of previous calculations when the CP-violating interaction is of isovector character.
