    "abstract": "We report ab initio correlated relativistic calculations of the effective\nelectric field W_d acting on the electron in two excited electronic states of\nPbO, required for extracting the electric dipole moment of the electron from an\nongoing experiment at Yale, which has the potential of improving accuracy for\nthis elusive property by several orders of magnitude. The generalized\nrelativistic effective core potential and relativistic coupled cluster methods\nare used, followed by nonvariational one-center restoration of the\nfour-component wavefunction in the heavy atom core. W_d is -3.2\\times 10^24\nHz/ecm for the a(1) state and -9.7\\times 10^24 Hz/ecm for the B(1) state.\nComparison of calculated and experimental values of the hyperfine constant\nA_{\\parallel} provides an accuracy check for the calculation.",
