Fig. 3.
Cross-section ratios of 4He, 12C and 56Fe to 3He, normalized to mass A, as a function of x for Q2 > 1.4 GeV2. The horizontal lines indicate two scaling levels of the cross-section ratios. Solid parts of the lines show the scaling regions used to calculate the per-nucleon probabilities for two- and three-nucleon correlations in helium-4, carbon and iron.
