Abstract
Using coherent bremsstrahlung at MAMI (Mainz), the beam asymmetry of the differential cross sections for coherent photoproduction on has been measured in the energy interval from 200 to 500 MeV at an angle of . The coherent ( ) reaction is used as a precise linear polarimeter for the first time. Agreement with predictions has been obtained on a level of precision.
