Abstract

Experiment E97-006 was performed at JLab in Hall C to measure the spectral function S(E _m , P _m ) via (e,e'p) for the nuclei C, Al, Fe, Au in the region of high missing energy E_m and missing momentum P_m. To study short-range correlations as well as the reaction mechanism beyond PWIA data were taken in parallel and perpendicular kinematics covering a P_m range of up to 800 MeV/c. Assuming PWIA the spectral function can be extracted from the data. Preliminary results of the spectral function are compared to the Correlated Basis Function theory of Benhar and the Green's function approach of Müther et al.. The spectral functions obtained for different targets are compared as well.
