From Phase Shifts of (np)-scattering to the Relativistic Deuteron Form Factor Session FB03 - Nuclear Theory. ORAL session, Monday afternoon, March 22 Room 203E, GWCC Andrei V. Afanasev (North Carolina Central University, Durham, NC 27707 and Jefferson Lab, Newport News, VA 23606), V.D. Afanas'ev, S.V. Trubnikov (Kharkov State University, Kharkov 310077, Ukraine), NCCU-Kharkov Team
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(Q^2). The results of numerical calculations of
|G_Cd(Q^2)| are presented in the interval of the
four--momentum transfers squared \mbox 0 \leq Q^2 \leq
35\:fm^-2. Zero and the prominent secondary maximum in
|G_Cd(Q^2)| are the direct consequences of the change of
sign in the experimental ^3S_1 -- phase shifts. Till the
point Q^2 \simeq 20 \;fm^-2 the total relativistic
correction to |G_Cd(Q^2)| is positive and reaches the
maximal value of 25% at Q^2 \simeq 14 fm^-2.
Predictions for the related Jefferson Lab experiments are
discussed.
