Description

Within the framework of a relativistic single-particle model, final state interaction between outgoing nucleons and residual nuclei and Coulomb distortion of charged current reaction are studied through total cross sections of neutrino-nucleus scattering . The Coulomb effect is almost half of the electron scattering. Furthermore, to investigate the effect of the final state interaction, a relativistic phenomenological optical potential and a real potential for final nucleons are used. We calculate both neutral-current reaction such as $(\nu, \nu')$ and charged-current reaction like $(\nu_e, e^-)$ and $(\nu_{\mu}, \mu^-)$ with inclusion of the strangeness. In these calculations, $^{12}$C is used as a target nucleus and the incident neutrino (antineutrino) energies are exploited up to 2 GeV. We find that the effect of the final state interaction is about 50 \% for the optical potential and is about 15 \% for the real potential.
