摘要
The universal extrapolation (not interpolation) formula is justified through a complex angular momentum Regge pole representation of the electron differential cross sections. It is further demonstrated, using the recent forward electron scattering method for optically allowed transitions, that some of the sophisticated theoretical calculations are unreliable at and near zero scattering angles.
