Precision measurement of radiative neutron \b{eta}-decay: methodology and systematic effects

J. S. Nico, R. Alarcon, M. J. Bales +18

In the Standard Model the free neutron decays to a proton, an electron, and an antineutrino along with a continuous spectrum of photons. In 2016 the RDK II collaboration reported o…

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…

Comments on Systematic Effects in the NIST Beam Neutron Lifetime Experiment

F. E. Wietfeldt, R. Biswas, J. Caylor +10

We discuss issues raised by Serebrov, et al. in a recent paper regarding systematic effects in the beam neutron lifetime experiment performed at NIST. We show that these effects we…

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…

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…

A Comment on "The possible explanation of neutron lifetime beam anomaly" by A. P. Serebrov, et al

F. E. Wietfeldt, R. Biswas, R. W. Haun +10

We comment on a recent manuscript by A. P. Serebrov, et al. regarding residual gas charge exchange in the beam neutron lifetime experiment
