This vanishing point has an experimentally observable signature: When a beam of suitably aligned ground state PbF molecules is allowed to traverse a region of electric and magnetic flelds, the polarization is conserved when the electric fleld matches this magic value. By measuring the (molecular-frame)magnitude of this magic electric fleld for the case that the electric fleld is parallel or antiparallel to the magnetic fleld, sensitivity to the e-EDM is achieved. Progress toward this measurement, including the development of a continuous molecular beam source of PbF, characterization of the electronic, rotational, and hyperflne structure of the molecule, the achievement of an ultra-sensitive continuous ionization detection scheme, and the construction of a Ramsey- resonance machine are brie∞y summarized.Read More
