The WJC2 covariant spectator model reproduces electron-deuteron elastic scattering up to Q about 1.4 GeV by fitting two off-shell nucleon form factors and then extrapolating the neutron charge form factor to higher momentum transfer.

abstract
Tensor polarization observables (t20, t21 and t22) have been measured in elastic electron-deuteron scattering for six values of momentum transfer between 0.66 and 1.7 (GeV/c)^2. The experiment was performed at the Jefferson Laboratory in Hall C using the electron HMS Spectrometer, a specially designed deuteron magnetic channel and the recoil deuteron polarimeter POLDER. The new data determine to much larger Q^2 the deuteron charge form factors G_C and G_Q. They are in good agreement with relativistic calculations and disagree with pQCD predictions.

Covariant Spectator Theory of $np$ scattering: Deuteron form factors
The WJC2 covariant spectator model reproduces electron-deuteron elastic scattering up to Q about 1.4 GeV by fitting two off-shell nucleon form factors and then extrapolating the neutron charge form factor to higher momentum transfer.
