As a test of time-reversal invariance in electromagnetic interactions, a measurement was made of a T -invariance-forbidden polarization of the Λ 0 in the decay Σ 0 → Λ 0 + e + + e - . The result of this experiment, combined with a previous measurement (also using stopping K - mesons in hydrogen bubble chambers as a source of Σ 0 hyperons), is a polarization of (3±6)%.
