The decay →ne-ν̄ was studied using a hyperon beam at the Brookhaven alternating-gradient synchrotron. The and e- momenta were measured by magnetic spectrometers with magnetostrictive wire spark chambers. A threshold Cherenkov counter and a total-absorption calorimeter identified the electron and neutron, respectively. From a sample of 3507 reconstructed events we have found |gAgV|=0.435±0.035.
