Abstract:

We propose an extension to Jefferson Lab Experiment E89-008, an inclusive electron-nucleus scattering experiment in the domain of large $x$ and $Q^2$. Additional measurements with a 6 GeV beam would allow study of the scaling behavior at large $Q^2$ and provide important constraints on the components of the nuclear wave function at large momentum and removal energy. Measurements with few-body nuclei ($^2$H, $^3$He, and $^4$He) and a range of heavy nuclei (C, Cu, and Au) allow contact with theoretical calculations via essentially ``exact'' calculations for few-body systems and extrapolation of the heavier systems to potentially calculable nuclear matter. In addition, direct comparisons of heavy nuclei to deuterium and $^3$He at large $x$ will allow us to examine the nature of the short range correlations that generate the high momentum nucleons.
