Near edge electron energy loss spectroscopy: Comparison to x-ray absorption

Abstract

Inelastic electron scattering provides a convenient, lab-based alternative to bremsstrahlung or synchrotron radiation X- ray spectroscopy for inner-shell excitation studies of gases, solids and surfaces. The current capabilities of inner-shell electron energy loss spectroscopies (ISEELS) are reviewed and compared to X-ray techniques. Issues discussed include: momentum transfer dependence, oscillator strength determination, spatial and energy resolution, orientational sensitivity. Examples are given of the application of EELS to gases, solids and surfaces. © 1993 The Japan Society of Applied Physics.
