Abstract

The transparency of carbon for $(p, 2 p)$ quasielastic events was measured at beam momenta ranging from 5.9 to $14.5 GeV / c$ at 90° c.m. The four-momentum transfer squared $(Q^{2})$ 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 $9 GeV / c$ and a reduction to approximately the Glauber level at higher energies.
