    "abstract": "If electrons had an electric dipole moment (EDM) they would induce EDMs of\natoms. The ratio of the atomic EDM to the electron EDM for a particular atom is\ncalled the enhancement factor, R. We calculate the enhancement factor for the\nfrancium and gold atoms, with the results 910 plus/minus 5% for Fr and 260\nplus/minus 15% for Au. The large values of these enhancement factors make these\natoms attractive for electron EDM measurements, and hence the search for\ntime-reversal invariance violation.",
