The aCORN experiment uses a novel asymmetry method to measure the electron-antineutrino correlation (a-coefficient) in free neutron decay that does not require precision proton spectroscopy. aCORN completed two physics runs at the NIST Center for Neutron Research. The first run on the NG-6 beam line obtained the result a = 0.1090 +/- 0.0030 (stat) +/- 0.0028 (sys), the most precise to date. The second run on the new NG-C high flux beam line promises an improvement in precision to ¡ 2%. In addition we show that an improved measurement of the neutrino asymmetry (B-coefficient) can be made using the aCORN apparatus on a highly polarized neutron beam.

Spin Direction

The coefficient of the angular correlation between the electron direction and the neutron spin direction in the beta decay of the neutron has been measured using a beam of polarized neutrons. The coefficient of this correlation is −0.09 ± 0.05. This implies that CA/CV, the ratio of the axial vector to vector coupling constants in neutron decay, is equal to −1.20 ± 0.12.
