Abstract

In the reaction $π^{-} + p \to π^{-} + ρ^{0} + p$ at 8 GeV/c, we find that the $A_{1}$ can be explained as a kinematic effect due to a Deck-type mechanism, but only if both $π$ and $ρ$ exchanges are included. We also present evidence for a possible $π^{-} ρ^{0}$ resonance at 1190 MeV with a width of 17 MeV.
