    No full text
    The ÎŁ\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.Comment: 8 pages, 9 figures, 1 table, resubmitted to Phys. Rev.
