Abstract
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)×10−24 e cm. If we assume the theoretical ratio da/de=−600, this yields de=(−2.7±8.3)×10−27 e cm.Keywords
