Abstract

The a(1) state of PbO can be used to measure the electric dipole moment of the electron d_e. 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|W_d|d_e\ensuremath≥2.4\ifmmode×\else\texttimes\fi10²⁵ Hz[\fracd_ee cm].
