Abstract

Relativistic integral representation in terms of experimental neutron-proton scattering phase shifts is used to compute the charge form factor of the deuteron G_Cd(Q²). The results of numerical calculations of |G_Cd(Q²)| are presented in the interval of the four-momentum transfers squared 0 ≤ Q² ≤ 35 fm^-2. Zero and the prominent secondary maximum in |G_Cd(Q²)| are the direct consequences of the change of sign in the experimental ³S₁ - phase shifts. Till the point Q² ≃ 20 fm^-2 the calculated total relativistic correction to |G_Cd(Q²)| is positive and reaches the maximal value of 25% at Q² ≃ 14 fm^-2.
