Abstract
Absolute differential cross sections for the reaction ep to ep gamma have been measured at a four-momentum transfer with virtuality Q/sup 2/=0.33 GeV/sup 2/ and polarization epsilon =0.62 in the range 33.6 to 111.5 MeV/c for the momentum of the outgoing photon in the photon-proton center of mass frame. The experiment has been performed with the high-resolution spectrometers at the Mainz Microtron MAMI. From the photon angular distributions, two structure functions which are a linear combination of the generalized polarizabilities have been determined for the first time.
