An investigation of the time-reversal--odd angular correlation sigma-circumflexx(J x p/E) in /sup 19/Ne ..beta.. decay is reported. In this correlation, sigma-circumflex, p, and E are the ..beta.. spin, momentum, and energy, respectively, and J is the initial /sup 19/Ne spin. The sample was polarized by an atomic beam method and the ..beta.. polarization was measured with four Mott-scattering polarimeters. The magnitude R of the angular correlation is found to be -0.079 +- 0.053, consistent with time-reversal invariance. This result also implies Im(C/sub S/C/sub A/() = 0.19 +- 0.13.
