Neutron Polarimetry Using a Polarized 3He Cell for the aCORN Experiment
B. C. Schafer, W. A. Byron, W. C. Chen +7
The neutron polarization of the NG-C beamline at the NIST Center for Neutron Research was measured as part of the aCORN neutron beta decay experiment. Neutron transmission through…
Fundamental Neutron Physics: a White Paper on Progress and Prospects in the US
R. Alarcon, A. Aleksandrova, S. BaeÃler +88
Fundamental neutron physics, combining precision measurements and theory, probes particle physics at short range with reach well beyond the highest energies probed by the LHC. Sign…
The aCORN Backscatter-Suppressed Beta Spectrometer
M. T. Hassan, F. Bateman, B. Collett +13
Backscatter of electrons from a beta spectrometer, with incomplete energy deposition, can lead to undesirable effects in many types of experiments. We present and discuss the desig…
Measurement of the neutron decay electron-antineutrino angular correlation by the aCORN experiment
M. T. Hassan, W. A. Byron, G. Darius +12
The aCORN experiment measures the neutron decay electron-antineutrino correlation (-coefficient) using a novel method based on an asymmetry in proton time-of-flight for events w…
Recoil-Order and Radiative Corrections to the aCORN Experiment
F. E. Wietfeldt, W. A. Byron, B. Collett +8
The aCORN experiment measures the electron-antineutrino -coefficient in free neutron decay. We update the previous aCORN results to include radiative and recoil corrections to f…
Measurement of the electron-antineutrino correlation in neutron beta decay: aCORN experiment
F. E. Wietfeldt, W. A. Byron, G. Darius +9
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 spe…
