  • We have measured the ratio g1pF1p over the range 0.02901g1p(x,>Q2) dx at fixed Q2=3 (GeV/c)2 yields 0.127±0.004(stat)±0.010(syst), in agreement with previous experiments, but well below the Ellis-Jaffe sum rule prediction of 0.160±0.006. In the quark-parton model, this implies Δq=0.27±0.10. © 1995 The American Physical Society.
