| Abstract: | Events with a single highp T charged particle were recorded with the Split-Field-Magnet Detector in proton-proton collisions at the CERN-ISR. In the jet opposite to the trigger region the densities of photons and reconstructed neutral pions were measured with a liquid argon shower counter. Scaled momentum distributions of these particles are given and compared with those of charged pions. The spectra of charged and neutral pions coincide. The production cross-section of neutrals in the away jet shows no dependence on the flavour of the trigger particle. |
