A new experimental upper limit on the "time-reversal" coefficient D is reported for the allowed beta decay Ne 19 → F 19 + e + + ν e . The result, expressed in terms of the relative phase angle between axial-vector ( A ) and vector ( V ) couplings, is φ A , V ( Ne 19 ) = 180.2 ± 0.4 ∘ , consistent with T invariance. A nuclear-spin-polarized atomic beam of Ne 19 in which either of the magnetic substates m I = ± 1 2 can be selected, is allowed to terminate its flight in a cell, where the Ne 19 atoms remain for approximately four seconds without substantial spin depolarization. Delayed coincidences between positrons and F 19 -recoil ions from decays in the cell are observed and correlated with nuclear spin to determine D . The Ne 19 nuclear polarization is monitored continuously by observation of the beta-decay asymmetry.
