We determined the structure function ratio R^d_EMC=F^d₂/(Fⁿ₂+F^p₂) from recently published Fⁿ₂/F^d₂ data taken by the BONuS experiment using CLAS at Jefferson Lab. This ratio deviates from unity, with a slope dR^d_EMC/dx=−0.10 ± 0.05 in the range of Bjorken x from 0.35 to 0.7, for invariant mass W>1.4 GeV and Q²>1 GeV² . The observed EMC effect for these kinematics is consistent with conventional nuclear physics models that include off-shell corrections, as well as with empirical analyses …
