Abstract

We report on a new measurement of the time-reversal-violating triple angular correlation between the nuclear spin and the positron and neutrino directions

D \hat{J} \cdot ({\vec{v}}_{β} \times {\hat{q}}_{ν})

. Our result for the decay process

{}^{19}{Ne} \to {}^{19}{Fe}^{-} + e^{+} + ν

D = - 0.0005 \pm 0.0010

, consistent with time-reversal symmetry.
