Abstract

The reaction pn → Δ⁺⁺Δ^- with σ = 1.1 ± 0.2 mb is studied at 6.98 GeV/c. Comparison with the reactions pp → ΔΔ and pp → ΔΔ at different incident momenta shows that their cross section behaves like P_lab^-2.5±0.3, consistent with one-pion exchange. The production and decay of Δ⁺⁺Δ^- at small momentum transfer agrees with the OPE model with sharp cut-off at R = 1.3 fm. The decay correlations are also compared with some quark-model predictions.
