Description

We describe a search for the electric dipole moment de of the electron, carried out with 205Tl atoms in the ground state. The experiment makes use of the separated-oscillating-field magnetic-resonance method, laser state selection, fluorescence detection, and two counter-propagating atomic beams. Very careful attention is paid to systematic effects. The result for the atomic electric dipole moment is da = (1.6 ± 5.0) x 10-24 e cm. If we assume the theoretical ratio da/de = -600, this yields de = (-2.7 ± 8.3) x 10-27 e cm. 17 refs., 7 figs., 1 tab
