Abstract The electron virtual photon spectrum is calculated for a finite nucleus in distorted wave methods for E1, E2, E3 and M1 transitions. Evaluation of the external radial integrals is made in terms of a series of incomplete gamma functions. Internal radial integrals are evaluated using charge and current distributions which are model independent up to an incident electron energy of about 200 MeV.
