Measurement of the Electric Form Factor of the Neutron at MAMI Original Research Article

At the Mainz Microtron the electric form factor of the neutron, GE,n, has been measured in two kinds of double polarisation experiments. The most recent results have been obtained by recoil polarimetry from the quasi-elastic View the MathML source reaction at squared four-momentum transfers View the MathML source. A further data point at View the MathML source has been extracted from quasi-elastic scattering of polarised electrons on View the MathML source. We present the methods and results of our experiments as well as an overview on the precise GE,n data available at present.
