摘要：

About 12 000 events with six prongs have been measured in 16 GeV/c π-p interactions. Cross sections for the various reaction channels and for the production of mesonic baryonic resonances are given. In the reaction π-p → pπ+π+π-π-π-, the (π-π-π+) effective mass spectrum shows indications of enhancements near the A1, A1.5 and A2-meson masses. The longitudinal momentum distributions and the average transverse momenta are presented. The distribution of the angles between pairs of pions is studied and it is shown that in π-p interactions the average opening angle for pairs of positive pions is smaller than that for pairs of negative pions. © 1968.
