The -beam asymmetry Σ in the photoproduction of negative pions from quasi-free neutrons in a deuterium target was measured at Graal in the energy interval 700 – 1500 MeV and a wide angular range, using polarized and tagged photons. The results are compared with recent partial wave analyses.

The American Physical Society was founded on May 20th, 1899, when 36 physicists gathered at Columbia University with that aim. They proclaimed the mission of the new Society to be “to advance and diffuse the knowledge of physics”. This has since been the goal of the APS through scientific meetings and journal publication, as well as other activities. In 1913, the APS took over the operation of the Physical Review, which had been founded in 1893 at Cornell, and journal publication became its second major activity.
Physical Review C (PRC) contains research articles reporting experimental and theoretical results in all aspects of nuclear physics, including the nucleon-nucleon interaction, few-body systems, nuclear structure, nuclear reactions, relativistic nuclear collisions, hadronic physics and QCD, electroweak interaction, symmetries, and nuclear astrophysics.
