Description
The aCORN experiment uses a novel “wishbone 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 in 2013–2014 obtained the result $a =0.1090 \pm 0.0030 \mathrm{(stat)} \pm 0.0028 \mathrm{(sys)}$, a net uncertainty of 3.8%. The second run on the new NG-C high flux beam line promises an improvement in precision to $<$2%. Details of the experiment and data analysis will be presented.
