Popis: The reactions K − p → K N 3π are studied at 10 and 16 GeV/ c . Evidence is presented for the diffractive dissociation processes K → K 3π and p → N 3π , based on the observation, in the reactions involving no exchange of charge, of threshold enhancements in the K 3π and N3 π mass spectra with cross sections weakly dependent on energy. In the charge exchange reactions, the K 3π and N 3π spectra increase smoothly from threshold, and their energy dependence is strong. The most important decay channels contributing to the K → K 3π diffractive systems are K ω, K 1420 ∗ π and the two-resonance channel K 890 ∗ ϱ . For p → N3 π , major decay channels are pω and Δππ. For a fixed mass, it is found that the slopes of the d σ /d t ′ distributions are approximately the same as those observed for diffractive dissociation into lower multiplicities.
