Abstract

The ratio g₁ F₁ has been measured over the range 0.03 < x < 0.6 and 0.3 < Q² < 10 (GeV/c)² using deep-inelastic scattering of polarized electrons from polarized protons and deuterons. We find g₁ F₁ to be consistent with no Q²-dependence at fixed x in the deep-inelastic region Q² > 1 (GeV/c)². A trend is observed for g₁ F₁ to decrease at lower Q². Fits to world data with and without a possible Q²-dependence in g₁ F₁ are in agreement with the Bjorken sum rule, but Δ_q is substantially less than the quark-parton model expectation.
