Abstrakt: The coherent production of 3π systems by charged current antineutrino interactions on neon nuclei is studied in the bubble chamber BEBC exposed to the CERN SPS wide band beam. The coherent signal is attributed mainly to (ρπ) production, where the (ρπ) system is either non-resonant or comes from the decay ofa1 mesons. The kinematical variables and the total cross section are compared with the predictions of the meson dominance model.
