Arneodo M, Arvidson A, Badelek B, et al. Accurate measurement of F-2(d)/F-2(p) and R(d)-R(p). Nucl.Phys. B. 1997;487(1-2):3-26.Results are presented for F-2(d)/F-2(p) and R(d) - R(p) from simultaneous measurements of deep inelastic muon scattering on hydrogen and deuterium targets, at 90, 120, 200 and 280 GeV. The difference R(d) - R(p), determined in the range 0.002 0.1 the ratio decreases with Q(2)
