Improvements in Depth Selective Electron Moessbauer Spectroscopy

The conditions for achievement of high resolving power of depth selective conversion electron Moessbauer spectroscopy method at a combined installation 'electron spectrometer-nuclear gamma-resonance spectrometer' have been obtained. There has been made a considerable step in development of the method at its realization at a magnetic sector electron spectrometer with double focusing, equipped with electron source (a sample under investigation) of large-area and position-sensitive detector. The paper presents a prospective symmetrical version of a magnetic sector electron spectrometer that allows realizing more completely possibilities of the method. It is noted that the proposed method is particularly valuable for investigations of nanosystems, nanostrutures that contain Moessbauer nuclei.
