Résumé : Charged-current neutrino and antineutrino interaction cross sections have been measured in the energy range 10 to 50 GeV using BEBC filled with a neon-hydrogen mixture. At these energies, σ/E was measured to be (0.73±0.08) 10 -38 cm 2/GeV per nucleon for neutrinos and (0.32±0.06) 10 -38 cm 2/GeV per nucleon for antineutrinos. © 1979 Springer-Verlag.
