Remarks on depth selective CEMS — Backscattering measurements

Abstract

Depth Selective Conversion Electron Mossbauer (MB) Spectroscopy measurements usually are done in backscattering geometry under bad geometrical conditions due to low resonant count rates. Furthermore in the case of iron these investigations are often done on samples enriched with57Fe, partially polarized. Because of these conditions the spectra are modified more or less strongly by the cosine smearing effect and/or saturation effects due to high enrichment of57Fe. We have investigated these effects in the case of an α-Fe-metal sample using a high transmission orange spectrometer.
