Possible method for the determination of the neutron electric form factor based on a measurement of asymmetries for the process 2(H)over-right-arrow((e)over-right-arrow,e′n)p -: art. no. 025202

We generalize the recoil polarization method for the determination of the proton form factor to the case of the disintegration of vector polarized deuterons by longitudinally polarized electrons, (2)(H) over right arrow((e) over right arrow ,e'n)p. We suggest measuring for this reaction, in the kinematics of quasielastic en scattering, the ratio R-xz=A(x)/A(z) of the asymmetries induced by the x and z components of the deuteron vector polarization. Taking into account the final np interaction through the experimental np phase shifts, in the framework of the relativistic impulse approximation the ratio R-xz is sensitive to G(En) in a wide interval of momentum-transfer squared, whereas it depends weakly on the details of the np interaction and on the choice of the deuteron wave function. Moreover, in the range 0.5less than or equal toQ(2)less than or equal to1.5 GeV2, the ratio R-xz shows a smooth dependence on Q(2), making the analysis simpler.
