Near-threshold $\pi^-$ photoproduction on the deuteron

Nuclear Experiment 2020-03-25 v2

Abstract

The first experimental investigation of the near-threshold cross section for incoherent π\pi^- photoproduction on the deuteron γ\gamma d -> π\pi^- pp is presented. The experimental technique involved detection of the ~131 MeV gamma ray resulting from the radiative capture of photoproduced π\pi^- 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 γ\gamma n -> π\pi^- p and pion-nucleon and nucleon-nucleon final-state interactions.
