Abstract

We analyze the unpolarized and polarized electron-induced proton-knockout reactions on O16O^{16} in different kinematical settings using two theoretical approaches. The first one is based on a relativistic mean-field distorted-wave description of the bound and scattering states of the proton, including a fully relativistic electromagnetic current operator. The second approach adopts the same current operator, but describes the proton properties consistently on the basis of microscopic calculations of the self-energy in O16O^{16} below the Fermi energy and final-state damping in nuclear matter above the Fermi energy, using the same realistic short-range and tensor correlations. Good agreement with all unpolarized and polarized data is obtained at low and high Q2Q^2 by using the same spectroscopic factors fixed by the low-Q2Q^2 analysis, indicating that a high degree of internal consistency has been reached.
