Abstract

The $π^{-} + p$ $T = \frac{1}{2}$ , $J = {\frac{1}{2}}^{-}$ scattering length and phase shift are calculated in a coupled-channel model of $π - N$ and $η - N$ scattering. The $η - n$ system is treated as a Regge pole associated with quasibound state. The Born terms associated with $ρ$ and nucleon exchange are included in the calculation. The results are compared with experimental data.
