Electron scattering from nuclei, provides us with an invaluable tool to probe the wide variety of nuclear and nucleonic properties, because it has proven itself as one of the most effective methods of studying the properties of the energy levels of atomic nuclei, so it has provided a wealth of information, mapping out nuclear ground state charge densities and precise transition charge and current densities for the excitation of single particle states and for collective states. In the electron scattering, the target is probed through the well understood electromagnetic interaction. Since the interaction is relatively weak, the measurement can be made on the target nucleus without greatly disturbing its structure. With electron scattering the cross section can be related to the transition matrix elements of the local charge and current density operators, and thus directly to the structure of the target nucleus itself. Electron scattering allows the variation of three-momentum transferred q to the target while the excitation energy is kept fixed.
