## Abstract

We have measured the neutron structure function g^{n}_{2} and the virtual photon-nucleon asymmetry A^{n}_{2} over the kinematic range 0.014 ≤ x ≤ 0.7 and 1.0 ≤ Q^{2} ≤ 17.0 by scattering 48.3 GeV longitudinally polarized electrons from polarized ^{3}He. Results for A^{n}_{2} are significantly smaller than the √R positivity limit over most of the measured range and data for g^{n}_{2} are generally consistent with the twist-2 Wandzura-Wilczek prediction. Using our measured g^{n}_{2} we obtain results for the twist-3 reduced matrix element d^{n}_{2}, and the integral ∫ g^{n}_{2}(x) dx in the range 0.014 ≤ x ≤ 1.0. Data from this experiment are combined with existing data for g^{n}_{2} to obtain an average for d^{n}_{2} and the integral ∫ g^{n}_{2}(x) dx.
