Angular distribution of electrons scattered at three-nucleon nuclei,splitting them into a nucleon and a deuteron

The angular distributions of the electrons undergoing inelastic scattering at He³ and H³ nuclei (accompanied by the two-particle splitting of the nuclei) are derived, with and without allowing for the interaction between the nucleon and deuteron so formed. Interaction in the final state has a major effect on the calculated relationships, and due allowance for this interaction improves agreement between theory and experiment in relation to the calculated cross sections.
