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