Phys. Rev. Lett. 63, 965–968 (1989)New limits on the electron electric dipole moment from cesiumReceived 12 June 1989; published in the issue dated 28 August 1989 The electric-dipole moment (edm) of the ground state of cesium has been measured using a two-laser method that does not require the presence of an external B field. The measured value dCs=(-1.8±6.7±1.8)×10-24 e cm implies that the electron EDM is de=(-1.5±5.5±1.5)×10-26 e cm. This result represents more than an order-of-magnitude improvement over all previous limits. © 1989 The American Physical Society URL:
