The magnetic form factors of 3He and 3H with mesonic-exchange corrections: Effects of the D-state and the role of short-range correlations

We show that the D-state of the trinucleon and the short-range behavior of the S- and D-state wave functions are extremely important in determining the magnetic form factors of the three-body system. We present a complete calculation of the form factors taking into account the conventional impulse approximation for the nuclear current and contributions from mesonic exchange currents. The D-state wave function has been determined by perturbation theory.
