Abstract
Results are presented on a partial wave analysis of the ωη final state produced in π-p interactions at 18 GeV/c where ω → π+π-π0, π0 → 2γ, and η → 2γ. We observe the previously unreported decay mode ω(1650) → ωη and a new 1+- meson state h1(1595) with a mass M = 1594(±15)(-60+10)MeV/c2 and a width Γ = 384(±60)(-100+70) MeV/c2. The h1(1595) state exhibits resonant-like phase motion relative to the ω (1650).
