Abstract
An electron detector for conversion electron Moessbauer spectroscopy CEMS has been designed and built. Tests have been performed to study the effects on the detector resolution with respect to high voltage, gas flow rate, and counting rate. These parameters have been optimized to detect the 7.3keV conversion electrons emitted following resonant absorption of the 14.4keV source gamma rays associated with the Moessbauer effect using Fe57. CEMS spectra have been obtained using standard Fe57 enriched and natural iron samples. CEMS spectra have also been obtained for InPFe samples supplied by the Naval Research Laboratory. So far we have only been successful in observing the iron in the precipitates in these samples. Our tentative conclusions are that the precipitate regions contain a FeP2 component and perhaps regions of pure iron. We intend to study the precipitates further. Since our preliminary work has been completed, we now plan to make extensive tests to determine whether or not the CEMS technique can detect the substitutional iron in InPFe samples.
