“…(Color online) The intensity of the 6s, 7s, and 5d levels as a fraction of the elastic peak intensity for 500 eV electrons scattered from Xe. The experimental data are from Suzuki et al [7,8], and the theoretical values are from the theory described here. Note that the J = 1 transitions are sharply forward peaked, in contrast to the J = 3 transitions.…”

We study the inelastic excitations of Xe for electrons with relatively high energies (500 or 750 eV) scattered over large angles, both experimentally and theoretically. In particular, we focus on the shape and intensity of the spectra of inelastically scattered electrons at the sharp dip in the elastic cross section near 135 • at 750 eV. Under these conditions, the first Born approximation predicts virtually zero intensity. However, in reality, measurable intensity is observed. Calculations carried out using the relativistic distorted-wave method describe the measurements reasonably well. A comparison is made between the calculations and previously published high-resolution studies. Overall agreement is quite good, especially for the lowest-energy excitations, but substantial differences are found for certain higher levels. The theory reproduces quite well the variations in intensity of the inelastic excitations for measurements near the dip in the elastic-scattering cross section, somewhat surprisingly, as the theories for elastic scattering and inelastic scattering are developed along completely different lines.

“…By extrapolating the measured GOS to zero momentum transfer one obtains an estimate of the optical oscillator strength, and this was the main basis for early comparison of experiment with theory [2]. For neon the shape of the GOS was measured at incoming energies between 300 and 500 eV for different transitions, and it was shown that the monopole, dipole, and quadrupole transitions are all characterized by a specific shape of the GOS [3][4][5][6]. Ne was measured at higher energies as well (2500 eV), as the validity of the FBA should increase with energy [7].…”

Fast-electron scattering from Ne: A comparison of distorted-wave theory with experiment

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 135 • 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.
