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++.
