The differential cross section for π − p → n π o has been measured in detail from 150 to 600 MeV. The backward cross section has a previously unobserved dramatic dip at 425 MeV. We interpret this dip in terms of interference between the P 33 (1236) and the P 11 (1470) resonances. These data provide strong evidence for the adequacy of the phase shift solutions in this energy range.

Cross sections for π − p→n π o at 5.9, 10.1 and 13.8 GeV/ c incident momentum are presented in the angular region from 180 o to u , the crossed four-momentum transfer squared, of −2(GeV) 2 and the energy dependence is discussed. The cross section for π − p→n η o integrated over the same angular region at 5.9 GeV/ c is also presented.

π − p → π 0 n and π − p → η n differential cross sections have been measured in nine nuclei ranging from hydrogen to lead at a 7.82 GeV/ c beam momentum and in a range of t going from 0 to −2 (GeV/ c ) 2 . The results can be understood in the framework of the Glauber theory which allows in addition a determination of the π 0 and η total cross sections on nucleons.
