Phys. Rev. Lett. 52, 1096–1099 (1984)Evidence for Neutrino- and Antineutrino-Induced Coherent π0 ProductionReceived 21 April 1983; published in the issue dated 26 March 1984 The angular distribution of isolated photon conversion pairs, collected during the proton-synchrotron-Gargamelle ν and ν̅ Freon experiments, has been examined to determine whether any anomalous small-angle production is present. There is a definite excess of conversion pairs over what is expected from resonantly produced and neutron-induced π0's. This excess is in accord with ν-(ν̅ -) induced coherent π0 production off nuclei. © 1984 The American Physical Society URL:
