We investigate the rôle of RPA correlations in longitudinal and transverse response functions for inelastic electron scattering from 12C at momentum transfers ranging between 200 MeV/c and 550 MeV/c. We refer to a continuum self-consistent RPA theory with a SK3 interaction. Electromagnetic operators are taken for uncorrelated nucléons. The partial response on (e, e'p) and (e, e'n) reaction channels is also calculated. Since energy-weighted sum rules are conserved, we can control the effect of the Hartree-Fock non-locality expressed by the SK3 nucleon effective mass as well as the action of creation and descruction of 1p 1h pairs on the true ground state induced by the RPA residual interaction.
