Final results for the neutron ? -asymmetry parameter A 0 from the UCNA experiment

The UCNA experiment was designed to measure the neutron ?-asymmetry parameter A0 using polarized ultracold neutrons (UCN). UCN produced via downscattering in solid deuterium were polarized via transport through a 7 T magnetic field, and then directed to a 1 T solenoidal electron spectrometer, where...
