Abstract

Recent measurements are reviewed of the spin structure functions g 2 p and g 2 d measured at SLAC over the kinematic range 0.02 ≤ x ≤ 0.8 and 0.6 ≤ Q 2 ≤ 20 (GeV/c)2, made by scattering 29.1 and 32.3 GeV longitudinally polarized electrons from transversely polarized NH3 and 6LiDtargets. The future SLAC program includes an experiment (E161) to measure ΔG(x) through polarized open charm photoproduction. Dominance of the photon-gluon fusion process can be tested using linearly polarized photons. Another experiment (E159) will determine the high-energy convergence of the GDH sum rule for both proton and deuteron target.
