It is found in the reactions π ± p→( π ± π + π −)p, believed to be dominated by diffraction dissociation, that the dσ dt′ distributions show a “cross-over” effect at t′ ≈ 0.15, similar to the effect observed in elastic scattering. This gives evidence for the interference of ( ϱ 0, B 0,…)-exchanges with ( P, f 0, …) -exchanges in pion diffraction dissociation reactions. No such evidence is found for baryon dissociation, π ± p→ π ±(p π + π −), at the same energy.
