Abstract
If electrons had an electric dipole moment (EDM) they would induce EDM's of atoms. The: ratio of the atomic EDM to the electron EDM for a particular a tom is called the enhancement factor R. We calculate the enhancement factor for the francium and gold atoms, with the results 910 +/- similar to 5% fo r Fr and 260 +/- similar to 15% for Au. The large values of these enhanceme nt factors make these atoms attractive for electron EDM measurements, and h ence the search for time-reversal invariance violation. [S1050-2947(99)0620 4-6].
