Depth-Selective Conversion-Electron Mössbauer Spectroscopy

Abstract
A high-resolution, electrostatic electron spectrometer combined with a Mössbauer spectrometer has been used to obtain depth-selective Fe57 Mössbauer spectra from the surface region of an iron scatterer by detecting emitted conversion electrons at selected electron energies. Clear experimental evidence of a sharp depth resolution in the Mössbauer spectra is demonstrated for the first time, in accordance with theoretical predictions.
