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)x10(-28)e cm, which yields an upper limit /d(e)/ < or = 1.6x10(-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).
我们展示了最近在205Tl中寻找T违反的结果,该结果根据电子电偶极矩d(e)进行解释。我们发现d(e) = (6.9 +/- 7.4)x10(-28)e cm,在90%置信度下得出上限/d(e)/ ≤ 1.6x10(-27)e cm。当前设备是用于设定d(e)先前限制的原子束磁共振装置的重大升级。
