    "abstract": "The a(1) state of PbO can be used to measure the electric dipole moment of\nthe electron d_e. We discuss a semiempirical model for this state, which yields\nan estimate of the effective electric field on the valence electrons in PbO.\nOur final result is an upper limit on the measurable energy shift, which is\nsignificantly larger than was anticipated earlier: $ 2|W_d|d_e \\ge 2.4\\times\n10^{25} \\textrm{Hz} [ \\frac{d_e}{e \\textrm{cm}} ]$.",
