Inner-shell electron energy-loss spectroscopy of SF 6 at very high momentum transfer

Non-dipole S 2p and S 2s core excitation of SF 6 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...

Summary:Non-dipole S 2p and S 2s core excitation of SF 6 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.
