Final state effects in the 4He (e,e'd) d reaction

We study the effects of final state rescattering on the cross section for the He-4(e, e'D)D reaction. We find that for the kinematical region in which there exists published data these effects are especially important for the L = 0 and L = 2 partial waves. The L = 0 rescattering is mainly important for ensuring orthogonality thereby giving the cross section the correct low q-dependence. We show that reasonable models of the rescattering bring the calculated cross section much closer to experiment than previous published calculations. Transverse current contributions to the cross section are also discussed.
