The magnetic form factor G(mn) was measured via the ratio of cross sections
R = sigma(D(e,e'n))/sigma(D(e,e'p)) on the deuteron in the q(2)-range 0.07
-0.90 (GeV/c)(2) with high precision at the Mainz Microtron. In the ratio R
the dependence on the deutron structure cancels and the sensitivity to mes
on exchange currents and final state interactions is small. The efficiency
of the detector was measured at the high intensity neutron beam of Paul Sch
errer Institute.
We have also determined the electric form factor of the neutron G(en) via (
3)(H) over right arrow e(e,e'n) in quasi-elastic kinematics at 0.67 (GeV/c)
(2). G(en) is extracted from the asymmetry ratio A(perpendicular to)/A(para
llel to) which is measured with target spin perpendicular and parallel to t
he momentum transfer. Due to the dominance of the interference term G(mn) G
(en) this method provides a high sensitivity to the small quantity G(en)
