In order to test the Coulomb sum rule in nuclei, a precision measurement
of inclusive electron scattering cross sections in the quasi-elastic region was
performed at Jefferson Lab. Incident electrons of energies ranging from 0.4
GeV to 4 GeV scattered off 4He, 12C, 56Fe and 208Pb nuclei at four scattering angles (15 deg., 60 deg., 90 deg., 120 deg.) and scattered energies ranging from 0.1 GeV to 4 GeV. The Rosenbluth method with proper Coulomb corrections is used to extract the transverse and longitudinal response functions at three momentum transfers 0.55 GeV/c ~ |q| 1.0 GeV/c. The Coulomb Sum is determined in the same ~ |q| range as mentioned above and will be compared to predictions. Analysis progress and preliminary results will be presented.
