Gamma-Ray Spectrum in Coincidence with Scattered Pions from 190-MeVπ−Reactions onAl27

In a pion—$\gamma$-ray coincidence spectrum from 190-MeV ${\pi }^{-}$ reactions with ${}_{}{}^{27}{}_{}{}^{}\mathrm{Al}$, prominent lines are observed corresponding to the equivalent removal of ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$, $\alpha$, $t$, $d$, $p$, and $n$. When the data are normalized to $n$ removal and compared to the inclusive singles $\gamma$-ray data, pion-scattering cross sections on the order of (50-100)% of the total for these reactions are implied.
