A study of the reaction π−p→π−π+n at 6 GeV/c incident momentum has been made using the prism plot analysis (PPA) to reject multineutral contaminations and to separate various reaction channels (ρ0n, f0n, g0n, π−Δ+, π−(π+n)DD). We can improve separability of PPA by incorporating decay angular distributions of resonances. Cross sections, invariant mass distributions, and production and decay angular distributions are presented.
