Abstract

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