Measurement of the left-right asymmetry in the electrofission of the deuteron

At the Electron Stretcher Accelerator ELSA of the Bonn University the left-right asymmetry Aφof the reaction d(e,e'p)n has been measured in quasi-free kinematics (Ee=1.6 GeV, θe=14 ). The scattered electrons were detected with a magnetic spectrometer. Due to the high duty cycle of ELSA non-magnetic proton detectors could be used. Therefore a simultaneous measurement at different proton angles was possible, leading to small systematic errors. The remaining systematic errors have been studied carefully and corrected. The experimental data are in good agreement with theoretical calculations, if relativistic corrections are taken into account. (orig.)
