N2 - The reaction np → ppπ- has been studied in the incident-momentum range of 1 to 4 GeV/c using the DESY 85 cm HBC exposed to a neutron beam. The production of δ(1236) and other baryon states are examined. The reaction is analysed in terms of a one-pion-exchange model using the Dürr-Pilkuhn and Benecke-Dürr parametrisations. Taking Wolf's set of R parameters, apart from Rδ which was set to 1GeV-1, an adequate description of all features of the data is obtained. σ(np → ppπ-) as function of the neutron momentum is evaluated using the OPE model and the isospin relation between the δ production in np and pp reactions.
