A partial-wave analysis of the mesons from the reaction π- p → π+ π- π- π0 π0 p has been performed. The data show b1π decay of the spin-exotic states π1(1600) and π1(2000). Three isovector 2-+ states were seen in the ωρ- decay channel. In addition to the well known π2(1670), signals were also observed for π2 (1880) and π2(1970).
