Abstract
Using a transmission type polarimeter, an asymmetry has been found that can be ascribed to a circularly polarized component in the bremsstrahlung beam of unpolarized relativistic electrons from the Mainz electron linac, in the region of electron energiesE el between 140 and 400 MeV. The experiment is described in detail. Systematical errors are discussed. For a comparison with electroweak theory, an exact calculation for small photon emission angles (of the order ofm c 2/E el) is needed.
