摘要：

Non-dipole S 2p and S 2s core excitation of SF, has been studied using inelastic electron scattering with variable scattering angles and impact energies (momentum transfer (K), 0.9 < K-2 < 113 a.u.(-2)). A non-dipole excitation at 181 eV is found to be the dominant S 2p spectral feature at large momentum transfer. A variable impact energy, fixed-K study shows that the first Born approximation fails under low impact energy, large scattering angle conditions. This study illustrates the importance of exploring a wide range of the inelastic scattering surface to ensure proper understanding of molecular spectroscopy and scattering dynamics.
