The Momentum Transfer and Target Mass Dependence of the

In order to study some of the exclusive structure and reaction dynamics in the quasi elastic region, (e,e ^' p) measurements on ^{12}C and ^{63 }Cu were performed. These measurements attempt to isolate the nuclear reaction mechanism contribution from the off shell e-p cross section. We performed measurements at five three-momentum transfer |vec {rm q}| for each target, varying |vec{rm q} | by changing the electron scattering angle theta_{rm e^' }. The measurements were performed at the MIT -Bates Linear Accelerator Center. The measurements were compared with Impulse Approximation (IA) predictions, providing quantitative tests of the approximations involved. The measurements for the p-shells were emphasized: the ^{12}C 1p-shell and the ^{63}Cu 2p-shell. For both targets, missing energy spectra were extract up to 50 MeV. The data from the second major shell regions, the ^{12}C s-shell and the ^{63}Cu f-s shell, were also compared with IA predictions. Finally, the ^{12}C results were compared with existing ^{12}C(e,e ^' p) results.
