Abstract
We report a measurement of the magnitude of the helicity from -pair events taken with the CLEO detector at the CESR electron-positron storage ring. Events in which each undergoes the decay , with a charged pion or kaon, are analyzed for energy correlations between the daughter hadrons, yielding = , with the first error statistical and the second systematic.
