Abstract

The small angle scattering of $π^{+}$ and $π^{-}$ from ${}^{16}O$ has been measured at 155, 185, and 213 MeV laboratory kinetic energy. The real part of the forward scattering amplitude was extracted from the data. The real part extrapolates to zero at 163±3 MeV.

NUCLEAR REACTIONS ${}^{16}O (π^{\pm}, π^{\pm})$ , $E = 155 - 213$ MeV; measured $σ (θ_{π})$ ; deduced $\frac{Re f_{s} (0 °)}{Im f_{s} (0 °)}$ .
