Descripción
The Σ beam asymmetry in the photoproduction of neutral pions from
quasi-free nucleons in a deuteron target was measured for the first time
between 0.60 and 1.50GeV, with the GRAAL polarized and tagged photon
beam. The asymmetry values from the quasi-free proton were found equal
to the ones extracted from a pure proton target. The asymmetries from
quasi-free proton and quasi-free neutron were found equal up to 0.82GeV
and substantially different at higher energies. The results are compared
with recent partial-wave analyses.
