Beam asymmetry $\Sigma$ measurements on the ${\pi }^{-}$ photoproduction off neutrons

Abstract

The $\Sigma$ beam asymmetry 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.
