Abstract
The electric form factor of the neutron G(E,n) has been determined at the M ainz Microtron MAMI at the low momentum transfer Q(2) = 0.15(GeV/c)(2) in a measurement of the recoil polarisation ratio P-x/P-z in the quasifree reac tion D(e, e'n)p. At this Q(2) the influence of the nuclear binding is stron g. A purely kinematical model is used to get some insight into the effect o f the initial Fermi momentum distribution of the neutron. The influence of the final state interaction is determined quantitatively by a model of Aren hovel et al.. After the corresponding corrections a value of G(E,n)(0.15 (G eV/c)(2)) = 0.0481+/-0.0065(stat) +/- 0.0053(syst) is obtained.
