Description
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, 2H-vector(e-vector,e'n)p. We suggest measuring for this reaction, in the kinematics of quasielastic en scattering, the ratio Rxz=Ax/Az 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 Rxz is sensitive to GEn 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 0.5≤Q2≤1.5 GeV2, the ratio Rxz shows a smooth dependence on Q2, making the analysis simpler
