Near-threshold $\pi^-$ photoproduction on the deuteron.
2018
The first experimental investigation of the near-threshold cross section for incoherent $\pi^-$ photoproduction on the deuteron $\gamma$ d -> $\pi^-$ pp is presented. The total cross section has been measured using an unpolarized tagged-photon beam, a liquid-deuterium target, and three large NaI(Tl) spectrometers. The experimental technique involved detection of the ~131 MeV gamma ray resulting from the radiative capture of photoproduced $\pi^-$ in the target. The data are compared to theoretical models that give insight into the elementary reaction $\gamma$ n -> $\pi^-$ p and pion-nucleon and nucleon-nucleon final-state interactions.
