title = "Measurements of the Proton and Deuteron Spin Structure Function g2 and Asymmetry A2 ",
abstract = "We have measured proton and deuteron virtual photon-nucleon asymmetries [Formula presented] and [Formula presented] and structure functions [Formula presented] and [Formula presented] over the range [Formula presented] and [Formula presented] 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, [Formula presented]. Twist-3 matrix elements have been extracted and are compared to theoretical predictions.",
