Abstract
Photons produced in pi(-) p interactions at 280 GeV/c were detected by reconstructing the e(+)e(-) pairs produced via the materialisation of the photons in a 1 mm thick lead sheet placed in front of the MWPC's of the OMEGA spectrometer at CERN. A soft photon signal 7.8 +/- 1.5 ti mes the Q.E.D. inner bremsstrahlung prediction was observed confirming the results of a previous experiment. (C) 1997 Elsevier Science B.V.
