C 97, 035505 (2018) M.A.-P.Brown, for the UCNA Collaboration New result for the neutron β-asymmetry parameter A0 from UCNA RADIOACTIVITY 1n(β-); measured neutrons, β, nβ(θ) using polarized neutrons from Ultracold Neutron (UCN) source at Los Alamos Neutron Science Center (LANSC, LANL); deduced precise value A0 neutron-β- asymmetry parameter, ratio of weak axial-vector to vector coupling constants gA/gV, and Cabibbo-Kobayashi-Maskawa (CKM) matrix element Vud for 0+ 0+ superallowed β transitions; discussed systematic uncertainties. Comparison with previous experimental results.
