1. SLAC

The A-dependence of the quasielastic A(e, e{prime}p) reaction has been studied at SLAC with {sup 2}H, C, Fe, and Au nuclei at momentum transfers Q{sup 2} = 1, 3, 5, and 6.8 (GeV/c){sup 2}. We extract the nuclear transparency T(A, Q{sup 2}), a measure of the average probability that the struck proton escapes from the nucleus A without interaction. Several calculations predict a significant increase in T with momentum transfer, a phenomenon known as Color Transparency. No significant rise within errors is seen for any of the nuclei studied.
