Phys. Rev. Lett. 89, 133001 (2002) [4 pages]Enhancement of the Electric Dipole Moment of the Electron in PbOReceived 23 May 2002; published 4 September 2002 The a(1) state of PbO can be used to measure the electric dipole moment of the electron de. We discuss a semiempirical model for this state, which yields an estimate of the effective electric field on the valence electrons in PbO. Our final result is a lower limit on the measurable energy shift, which is significantly larger than was anticipated earlier: 2|Wd|de≥2.4×1025 Hz[de/e cm]. © 2002 The American Physical Society URL:
