Abstract
With a new detection method, the upper limit on the time-reversal-noninvariant triple angular correlation in the nuclear decay → + has been reduced. Polarized 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 , which is consistent with time-reversal symmetry.
