A Microscopic T-Violating Optical Potential: Implications for Neutron-Transmission Experiments

Abstract

We derive a T-violating P-conserving optical potential for neutron-nucleus scattering, starting from a uniquely determined two-body $\rho$-exchange interaction with the same symmetry. We then obtain limits on the T-violating $\rho$-nucleon coupling ${\overline{g}}_{\rho }$ from neutron-transmission experiments in ${}^{165}$Ho. The limits may soon compete with those from measurements of atomic electric-dipole moments.
