Progress towards measurement of the electron electric dipole moment using the $^{207}$Pb$^{19}$F molecule

ORAL

Abstract

The lead monofluoride molecule provides for a 1000- to 10,000- fold improvement in sensitivity to an electron electric dipole moment (e-EDM) over atomic-based measurements. In addition, unexpectedly closely spaced energy levels of opposite parity in the electronic ground state of $^{207}$Pb$^{19}$F along with its large dipole moment make this molecule an attractive candidate for improving the limit on the e-EDM. We present our progress towards a measurement of the e-EDM using $^{207}$Pb$^{19}$F, including a recently developed pseudo-continuous REMPI technique for detection from an effusive source.
