Measurements of the Q**2 dependence of the proton and deuteron spin structure functions g1(p) and g1(d)

The E143 collaboration Abe, K. ; Akagi, T. ; Anthony, P.L. ; et al.
Phys.Lett.B 364 (1995) 61-68, 1995.
Inspire Record 401107 DOI 10.17182/hepdata.28431

The ratio g1/F1 has been measured over the range 0.031 (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 Delta_q is substantially less than the quark-parton model expectation.
