Inner-Shell Excitation Of SO 2 And NO 2 By High Resolution Electron Energy Loss Spectroscopy--Comparison With Multichannel Quantum Defect Theory

Abstract

Electron energy loss spectra of the sulfur 2p, 2s and oxygen is inner-shells of SO2 and the nitrogen is and oxygen is inner-shells of NO2 have been obtained at high energy resolution (0.046-0.090 eV fwhm) under conditions of high impact energy (1-3.7 keV) and forward scattering. The measurements are compared with multichannel quantum defect theory calculations of the transition energies and dipole oscillator strengths. The experimental and calculated results are also compared with literature reports of measurements using synchrotron radiation.
