Abstract
Double-polarization observables in the reaction (e) over right arrow ep -> e'(p) over right arrow'gamma have been measured at Q(2) = 0.33 (GeV/c)(2). The experiment was performed at the spectrometer setup of the A1 Collaboration using the 855 MeV polarized electron beam provided by the Mainz Microtron (MAMI) and a recoil proton polarimeter. From the double-polarization observables the structure function P-LT(perpendicular to) is extracted for the first time, with the value (-15.4 +/- 3.3((stat.)-2.4) (+1.5) (syst.)) GeV-2, using the low-energy theorem for virtual Compton scattering. This structure function provides a hitherto unmeasured linear combination of the generalized polarizabilities of the proton.
