Abstract
We have measured the beta asymmetry A in the decay of free polarized neutrons, using the 4π superconducting spectrometer PERKEO II. The asymmetry parameter is A0 = −0.1189(12) corresponding to gAgV = −1.274(3). This value differs by three standard deviations from the one given by the Particle Data Group 1996. Our result contradicts earlier speculation on the existence of right-handed currents in neutron decay.
