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 d₄. We find d₄0ex{0ex}=0ex{0ex} (6. 97. 4) 10^-28ecm, which yields an upper limit |d₄|1. 610^-27ecm with 90% confidence. The present apparatus is a major upgrade of the atomic beam magnetic-resonance device used to set the previous limit on d₄.
Regan et al. (2002) studied this question.
