Abstract

A partial-wave analysis of the mesons from the reaction

π^{-} p \to π^{+} π^{-} π^{-} π^{0} π^{0} p

has been performed. The data show

b_{1} π

decay of the spin-exotic states

π_{1} (1600)

and

π_{1} (2000)

. Three isovector

2^{- +}

states were seen in the

ω ρ^{-}

decay channel. In addition to the well known

π_{2} (1670)

, signals were also observed for

π_{2} (1880)

and

π_{2} (1970)

.
