Title: Near-threshold π photoproduction on the deuteron

Abstract

The first experimental investigation of the near-threshold cross section for incoherent π - photoproduction on the deuteron γd → π - pp is presented. The experimental technique involved detection of the ≈ 131 MeV γ ray resulting from the radiative capture of photoproduced π - in the target. The total cross section was 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 γ n → π - p and pion-nucleon and nucleon-nucleon final-state interactions.
