Resumo$\ensuremath{\gamma}$ rays have been detected from 230-MeV negative pions incident on a water target. De-excitation $\ensuremath{\gamma}$ rays from $^{10}\mathrm{B}$, $^{12}\mathrm{C}$, $^{13}\mathrm{C}$, $^{14}\mathrm{C}$, $^{14}\mathrm{N}$, $^{15}\mathrm{N}$, $^{15}\mathrm{O}$, $^{16}\mathrm{O}$, and $^{16}\mathrm{N}$ have been identified and cross sections for excitation of particular residual states determined. Where necessary, the cross sections have been corrected for $\ensuremath{\gamma}$ feeding from higher states. Decays from short lived nuclear states result in Doppler broadened peaks which yield nuclear recoil momenta.NUCLEAR REACTIONS $^{16}\mathrm{O}({\ensuremath{\pi}}^{\ensuremath{-}},\ensuremath{\gamma}X)$, $E=230$ MeV, measured relative $\ensuremath{\gamma}$ yields at $\ensuremath{\theta}=90\ifmmode^\circ\else\textdegree\fi{}$.
