Abstract
The Electron Stretcher Accelerator ELSA of Bonn University delivers an external electron beam with a duty factor of up to 55%. Thus nonmagnetic detectors can be used to perform electron nucleon coincidence experiments with high precision. The magnetic form factor of the neutron G{sub m}{sup n} is determined by the so-called ratio method, i.e. G{sub m}{sup n} is extracted from the measured ratio of the cross sections of the d(e,e`n) and d(e,e`p) reactions in a region of quasi-free kinematics. Protons and neutrons are detected simultaneously in the same scintillation counter, so many systematic errors cancel out. The neutron detection efficiency is measured in situ by the associated particle method using the p({gamma},{pi}{sup +}n) reaction. For this reaction the high energy part of the photons produced by the electron beam in the target is used. The value of G{sub m}{sup n} found at a four momentum transfer of Q{sup 2} = 0.255 (GeV/c){sup 2} is (10.1 {+-} 3.8)% higher than the dipole value. (orig.)
