Extraterrestrial and terrestrial applications of the Mössbauer spectroscopy

Abstract

Mössbauer spectroscopy is a powerful technique used by physicists, chemists, geologists, biologists, metallurgists and scientists from other disciplines. A portable Mössbauer spectrometer, developed for extraterrestrial applications [1], opens up new industrial applications of MBS [1]. But for industrial applications it is also required to have a tool available for fast data analysis that should be easy to handle. The analysis of Mössbauer spectra and parameters is a barrier for a popularization of this wide-applicable spectroscopic technique in industry. Based on experience, it is time-consuming and requires the dedication of a specialist. But the analysis of Mössbauer spectra, from the fitting to the identification of the sample phases, can be fast using genetic algorithms, fuzzy logic and artificial neural networks [2]. Industrial applications are very specific ones and the data analysis can be performed using these algorithms. In combination with an automatic analysis, the Mössbauer spectrometer can be used as a probe instrument, which covers the main industrial applications. It is needed for on-line monitoring of products, processes and studies of case.
