This paper presents, for the first time, measurements of neutron transparency ratios nuclei relative to C measured using (e,e'n) reaction, spanning momenta 1.4 2.4 GeV/c. The were extracted in two kinematical regions, corresponding knockout mean-field nucleons and breakup Short-Range Correlated nucleon pairs. are consistent with each other regions agree proton transparencies from new previous (e,e'p) measurements, including those neutron-rich such as lead. data also confirm Glauber approximation that is commonly used interpret experimental data. nuclear-mass-dependence scales A^{\alpha} {\alpha} = -0.289 {\pm} 0.007, which nuclear-surface dominance reactions.
