  We report the results of a study of neutrino-carbon interactions at beam
energies ranging between few hundreds MeV and few tens of GeV, carried out
within the framework of the impulse approximation using a realistic spectral
function. The contributions of quasi elastic scattering, resonance production
and deep inelastic scattering---consistently obtained, for first time, from a
model based on a realistic description of the nuclear ground state---are
compared and analyzed.
