The transparency of carbon for (p,2p) quasielastic events was measured at beam momenta ranging from 5.9 to 14.5GeV/c at 90° c.m. The four-momentum transfer squared (Q2) ranged from 4.7 to 12.7(GeV/c)2. We present the observed beam momentum dependence of the ratio of the carbon to hydrogen cross sections. We also apply a model for the nuclear momentum distribution of carbon to obtain the nuclear transparency. We find a sharp rise in transparency as the beam momentum is increased to 9GeV/c and a reduction to approximately the Glauber level at higher energies.
