Abstract: Using linearly polarized tagged photons from coherent bremsstrahlung, differential cross sections and beam asymmetries for Compton scattering by have been measured at MAMI in the energy interval between 150 MeV and 500 MeV for scattering angles of θγlab=37°, 93° and 137°, thus largely increasing the available data base. Improved calculations in terms of the Δ-hole model completely fail to describe the data at large scattering angles. The same proved to be true for a schematic model, even after taking into account properties of nuclear photo-absorption in very detail.
