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 4He(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. (orig.)
