The electronic part of a possible P- and T-nonconserving neutral-weak-current-induced electric dipole moment in atomic Xe and Hg was calculated with many-body perturbation theory. After the effects of this P- and T-nonconserving interaction on all core orbitals were treated self-consistently, thereby including all single-particle effects to all orders but no correlation effects, the results μe=(5.2×10−23e m)CTσN and μe=−(6.0×10−22e m)CTσN, respectively, were obtained for Xe and Hg. The value for Xe can be combined with the recent experimental result, ∣∣μe(Xe129)∣∣<10−28e m, to give the upper limit ∣∣CT∣∣<2×10−6.
