A partial wave analysis of the 3π‐system has been performed for the reaction π + p → (π + π − π 0 ) Δ ++ (1232) at 16 GeV/c. Beside the well‐established A 2 0 (1300), the resonant state ω* with isospin I = 0 and spin‐parity J P = 3 − decaying mainly into (ϱπ) has been found. Its mass and width have been determined to be M = (1.71 ± 0.03) GeV and Γ = (0.22 ± 0.10) GeV. The cross section for the reaction π + p → ω* (1700) Δ ++ (1232) is σ = (12 ± 6) μb.
