New Limit on the Electron Electric Dipole Moment

We present the result of our most recent search for T violation in ²⁰⁵Tl, which is interpreted in terms of an electric dipole moment of the electron d_e. We find d_e = (6.9+/-7.4)×10^-28e cm, which yields an upper limit \|d_e\|<=1.6×10^-27e cm with 90% confidence. The present apparatus is a major upgrade of the atomic beam magnetic-resonance device used to set the previous limit on d_e.
