This paper presents the results of a study of the dominant neutral final states from π−p interactions. The data were obtained in an experiment performed at the Brookhaven National Laboratory Alternating Gradient Synchrotron, using a set of steel-plate optical spark chambers surrounding a liquid-hydrogen target. We present differential and total cross sections for the reactions (1) π−p→n+π0 and (2) π−p→n+η0(η0→2γ) and total cross sections for the reactions (3) π−p→n+kπ0 (k=2, 3, 4, and 5) and (4) π−p→all neutrals for eighteen values of beam momentum in the interval 1.3 to 4.0 GeV/c. The angular distributions for (1) and (2) have been analyzed in terms of expansions in Legendre polynomials, the coefficients for which are also given.

THE REACTION pi+ p ---> pi+ p pi0 pi0 AT 4-GeV/c: NO EVIDENCE FOR A NARROW epsilon

The Track Sensitive Target technique has been used to isolate 5000 events from the reaction π + p→ π + p π 0 π 0 at 4 GeV/ c . Channel cross sections are measured. The data agree with predictions from phase-shift analyses of π + π − data: the effect of the S ∗ is clearly seen. There is strong evidence against any narrow ϵ below 1 GeV/ c 2 .

π−p→π0n differential cross-sections have been measured in the region of small 4-momentum transfer at 40 GeV/c incident momentum. The experiment performed at the IHEP 70 GeV accelerator makes use of a hodoscope γ-spectrometer. Thet- dependence of the cross-section points to a dominance of the spin-flip amplitude.
