摘要：

We present the result of our most recent search for T violation in Tl-205, which is interpreted in terms of an electric dipole moment of the electron d(e). We find d(e) = (6.9 +/- 7.4) X 10(-28) e cm, which yields an upper limit \d(e)\ less than or equal to 1.6 X 10(-27)e 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).
