Quasifree (e, e′p) reactions at Q2 ∼ 0.1 GeV2 observed a strong quenching of the single-particle valence strength. This precluded unambiguous measurement of nuclear transparency in quasifree (e, e′p) reactions at Q2 ≥ 1 GeV2. We argue that the high-energy nuclear transparency in the transverse kinematics weakly depends on the probability of the short-range correlations and can be accurately determined using information on the cross section of the (e, e′) reaction at x ∼ 1 and Q2 ∼ 1-2 GeV2. We find that the Glauber approximation well describes E91-013 and NE18 (e, e′p) data at 2 ≤ Q2 ≤ 4 GeV2 without any significant quenching. This gives further support to our observation that the quenching of nuclear levels strongly depends on the resolution (Q2) and practically disappears at Q2 ≥ 1 GeV2.
