Abstract
A precise measurement of the neutron decay -asymmetry has been carried out using polarized ultracold neutrons (UCN) from the pulsed spallation UCN source at the Los Alamos Neutron Science Center (LANSCE). Combining data obtained in 2008 and 2009, we report , from which we determine the ratio of the axial-vector to vector weak coupling of the nucleon .
