AbstractWe have measured proton and deuteron virtual photon-nucleon asymmetries A2p and A2d and structure functions g2p and g2d over the range 0.03 < x < 0.8 and 1.3 < Q2 < 10 (GeV/c)2 by inelastically scattering polarized electrons off polarized ammonia targets. Results for A2 are significantly smaller than the positivity limit √R for both targets. Within experimental precision the g2 data are well described by the twist-2 contribution, g2ww .Twist-3 matrix elements have been extracted and are compared to theoretical predictions.
