The reaction π-p→pωπ- has been studied at 9.1 GeV/c, its total cross-section is σ=(123±22) μb. The pB− and the quasi-three-body channels contribute with cross-section of σ=(24±7) μb and σ=(94±23) μb, respectively. The main features of the quasi-three-body pωπ- channel, displayed by some techniques of data presentation, are satisfactorily described by a double-Regge-pole model. In this model pomeron-meson and meson-meson exchanges are taken into account. An OPE modelà la Veneziano predicts a total cross-section too high and reproduces very poorly the observed features.

We report a high-statistics measurement of the neutron-proton charge-exchange differential cross section for incident momenta 3 to 12 GeVc, and four-momentum transfers 0.003 to 0.85 (GeVc)2. The data are normalized absolutely to ±20%. The differential cross section is characterized by a sharp peak at small momentum transfers, with a gentler exponential behavior at large momentum transfers. This shape is remarkably independent of the incident momentum.
