Abstract

A limit on time reversal noninvariance is obtained by measuring the β-γ angular correlation in the decay of oriented Co56. From a search for a correlation of the form E1(J^•k^)(J^•p^×k^), where J^, p^, and k^ are unit vectors in the direction of the orientation axis, positron momentum, and photon momentum, respectively, we obtain E1=2ysinφ(1+v2)=-0.011±0.022, where yeiφ=CVMFCAMGT. RADIOACTIVITY Co56: measured βγ correlations from oriented nuclei, inferred limit on time reversal violation.
