| Abstract: | The result of a new run of measurements of the antineutrino escape asymmetry with respect to the spin of the decaying neutron is presented. The asymmetry coefficient is B=0.9821±0.0040, which is consistent with the prediction of the standard model of weak interactions. The prospects for increasing the accuracy of the measurements are discussed. Zh. éksp. Teor. Fiz. 113, 1963–1978 (June 1998) |
