Résumé :

The coherent production of and mesons in ()-neon charged-current interactions has been studied using the Fermilab 15-foot bubble chamber filled with a heavy Ne-H2 mix and exposed to the Tevatron quadrupole triplet (anti)neutrino beam. The () beam had an average energy of 80 GeV (70 GeV). From a sample corresponding to approximately 28 000 charged-current interactions, net signals of (539) coherent events and (197) 0 coherent events are extracted. For E>10 GeV, the coherent pion production cross section is determined to be (3.20.7)×10-38 cm2 per neon nucleus whereas the coherent production cross section is (2.10.8)×10-38 cm2 per neon nucleus. These cross sections and the kinematical characteristics of the coherent events at
