N2 - We compare electron-scattering data from Ne with first-order Born and distorted-wave calculations in an energy range between 300 and 2500 eV and for scattering angles up to 135â̂̃ and for energy losses up to the ionization energy. At small angles the distorted-wave calculations and first-order Born calculations are in good agreement, but at large momentum transfer the intensity predicted by the first-order Born theory drops off much faster than the experiment and distorted-wave calculations. The present distorted-wave calculations reproduce most of the experimental observations quite well, except for monopole transitions and near the minima in dipole-allowed s-to-p transitions. The first-order Born approximation fails completely at larger momentum transfer.
