With a new detection method, the upper limit on the time-reversal- noninvariant triple angular correlation J(pe×p)EeE in the nuclear decay Ne19 F19 + e++ has been reduced. Polarized Ne19 atoms from an atomic beam are captured in a holding cell, where the decay positrons and recoil ions are observed. The new value for the asymmetry parameter for this correlation is D=0.0040.0008, which is consistent with time-reversal symmetry.
