Abstract

Analyzing powers for $π p$ elastic scattering at bombarding energies below the $Δ (1232)$ resonance were measured at TRIUMF using the CHAOS spectrometer and a polarized spin target. This work presents $π^{-}$ data at six incident energies of 57, 67, 87, 98, 117, and 139 MeV, and a single $π^{+}$ data set at 139 MeV. The higher energy measurements cover an angular range of $72 ° <~ θ_{c . m .} <~ 180 °$ while the lower energies were limited to $101 ° <~ θ_{c . m .} <~ 180 ° .$ There is a high degree of consistency between this work and the predictions of the VPI/GWU group’s SM95 partial wave analysis.
