For the reaction π + p → ωΔ ++ data on the total cross section ( σ = 61 ± 12 μ b), differential cross sections, spin density matrix elements and statistical tensor elements are given. We observe natural and unnatural parity exchange contributions to the total cross section. We note that the value of ϱ 00 is not zero and in the helicity frame exhibits a dip at t ≈ −0.25 (GeV/ c ) 2 . A qualitative theoretical discussion of our results is presented.

The reaction K − d → K − π + π − n p s was studied in a bubble chamber experiment. The cross section was measured to be 1.3 ± 0.2 mb. The final state is dominated by K ∗0 (890) , K ∗0 (1420) and Δ − (1236) production. Partial cross sections, differential cross sections and decay angular distributions of the K ∗0 (890) δ − (1236) final state were found to give good agreement with the predictions of Białas and Zalewski obtained from the quark model. The final state K − π + Δ − (1236) is analyzed by use of the Van Hove plot.
