Abstract It is shown by analyzing theπ −1-nucleon interactions at 7 GeV that it is possible to select events which could be described by the one-pion exchange model. Among the 169 stars with identified recoil proton which were examined, there are approximately 17 events corresponding to the scheme having a nucleon in the lower vertex only, while the maximum number of cases having a pion-nucleon system there is 84, For the second group the distribution of the mass of particles emitted in the lower vertex has its maximum in the region of the nucleon isobar mass (T=3/2). The distribution of mass of particles emitted in the upper vertex is not in contradiction with the production ofζ andϱ mesons. The values of the square of the transferred four-momentum are distributed predominantly in the region of small values in agreement with the Salzman model.
