“…The recent neutrino experiments with accelerators have emphasized the importance of a global precise description of lepton scattering from nuclei at intermediate energies [1][2][3][4][5]. Although a great deal of progress has been achieved with models based on first principles description of the nuclear system [6], alternative approaches based on the spectral function [7,8] or the shell model [9], to mention some recent studies, have been put forward. As a general rule, the models cannot provide yet a complete description of the whole set of (e, e ′ ) data at the full range of kinematics needed, specially for high momentum and energy transfers, where a relativistic description becomes mandatory [10,11].…”
