Description
Conversion Electron Moessbauer Spectroscopy (CEMS) is a dual method to the more commonly used transmission or scattering Moessbauer spectroscopy. The same recoil-free nuclear resonance is the fundamental principle of the method; however, different product of the resonance is utilized. Instead of 14.41 keV photons (for the case of 57Fe), 7.3 keV conversion electrons together with 5.4 and 6.2 keV Auger electrons are detected. Comparison between natural vs. 57Fe enriched iron measurement is mentioned briefly as well as advantages and drawbacks of Depth Selective CEMS (DCEMS). A possible design of a gas-flow detector is presented.Three experimental results are presented in the paper, to demonstrate the power of CEMS with measuring thin surface layers. (authors)
