Nuclear transparency from quasielastic A(e,e'p) reactions uo to Q^2=8.1 (GeV/c)^2
Abstract
The quasielastic (e,e^\primep) reaction was studied on targets of deuterium, carbon, and iron up to a value of momentum transfer Q^2 of 8.1 (GeV/c)^2. A nuclear transparency was determined by comparing the data to calculations in the Plane-Wave Impulse Approximation. The dependence of the nuclear transparency on Q^2 and the mass number A was investigated in a search for the onset of the Color Transparency phenomenon. We find no evidence for the onset of Color Transparency within our range of Q^2. A fit to the world's nuclear transparency data reflects the energy dependence of the free proton-nucleon cross section.
