Abstract

The reaction $π^{-} + p \to π^{-} + p$ has been studied in the 15-in. bubble chamber at the Princeton-Pennsylvania Accelerator. The elastic scattering cross section was determined to be 8.5 ± 0.2 mb. The forward peak fits to an exponential in $t$ with a slope of 8.1 ± 0.2 ${(G e V / c)}^{- 2}$ . The forward differential cross section $\frac{d σ}{d Ω} (0) = 17.9 \pm 0.7$ mb/sr. A fit of the center-of-mass angular distribution to Legendre polynomials needed terms up to the 12th order, corresponding to the highest nonzero partial wave of $L = 6$ .
