    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 times
the Q.E.D. inner bremsstrahlung prediction was observed confirming the
results of a previous experiment. (C) 1997 Elsevier Science B.V."
