摘要：

The cross section asymmetry Sigma has been measured for the photoproduction of pi degrees mesons off protons, using polarized photons in the energy range E-gamma = 0.5-1.1 GeV. The center-of-mass angular coverage is theta (pi)* = 85 degrees -125 degrees with energy and angle steps of 25 MeV and 5 degrees, respectively. The obtained Sigma data, which cover the second and third resonance regions, are compared with existing experimental data and recent phenomenological analyses. The influence of these measurements on such analyses is also considered.
