“…The value of a, as extracted from data on coherent p0 production on nuclei [29], is = (10.8 + 0.4) GeV- 2 ; this value agrees with the one proposed by Rein and Sehgal [30] for the case of coherent single pion production, and used in [2]: b= 1/3RZu, RN= 1.12A 1/3 fm, where R N is the radius of the nucleus.…”

This is to be compared to an observed (9) coherent signal of (16+ 10) events, including (3___ 3) events attributed to single pion coherent production with emission of muon inner bremsstrahlung [2]. 3.…”

Abstract. Coherent production of p-mesons in charged current antineutrino interactions on neon nuclei is studied in the BEBC bubble chamber exposed to the CERN SPS wide band beam. The cross section is measured to be (95 + 25). 10 -40 em 2 per neon nucleus, averaged over the beam energy spectrum. The distributions of kinematical variables and the absolute value of the cross section are in agreement with theoretical predictions based on the CVC hypothesis and the vector meson dominance model.
