  title = {Prospects for an electron electric-dipole moment search in metastable ThO and ThF+},
  abstract = {The observation of an electron electric-dipole moment (EEDM) would have major ramifications for the standard model of physics. Polar molecules offer a near-ideal laboratory for such searches due to the large effective electric field ( F eff ), on order of tens of GV/cm that can be easily oriented in the laboratory frame. We present an improved method for simply and accurately determining F eff, in a heavy polar molecule, allowing for a quick determination of candidates for an EEDM experiment. We apply this method to ThO and Th F + , both of which possess metastable 3 Δ  electronic states. The values of F eff in ThO and ThF+ are estimated to be 104GV∕ cm  and  90 GV ∕ cm , respectively, making them two of the best known candidates for the EEDM search.},
