Abstract

pp interactions at 11 momenta in the range 0.9 to 2.0 GeV/c have been studied. The elastic angular distributions, covering the c.m. angular range 22°-90°, agree in general with Hoshizaki's phase-shift analysis which shows the looping ¹Dⁱⁿ and ³F₃ amplitudes in the Argand diagram. About 80% of pnπ⁺ events come from the nΔ⁺⁺ state at all momenta above 1.2 GeV/c. The behavior of the density matrix elements of the Δ⁺⁺ show no momentum or angular dependence. A large fraction of ppπ⁰ events also come from the pΔ⁺ state at all momenta above 1.2 GeV/c. The behavior of the Δ⁺ density matrix elements is similar to that for the case of Δ⁺⁺.
