Abstract

A sample of 6075 decays of unpolarized Ξ0 hyperons has been obtained in the Fermilab neutral-hyperon beam. All decay products from the sequence Ξ0→π0Λ, π0→γγ, Λ→pπ- were detected. Analysis of the proton asymmetry in the Λ decay gave αΞ0αΛ=-0.317±0.027 or αΞ0=-0.490±0.042. A comparison with the world average for αΞ- gives a ΔI=32 amplitude of 25 ± 9%.
