Properties of focusing polycapillary utilized in 57Fe Mössbauer spectroscopy

Popis výsledku v původním jazyce

A focusing polycapillary was incorporated in the Mossbauer spectrometer to achieve Mossbauer spectrum from the point with the diameter of 150 mu m. Since such an apparatus is rather unique and so far it has not been described, a detailed views into the problematics of using the focusing polycapillary with Co-57 source, and into the problematics of the scanning transmission Mossbauer microscope alignment procedure are presented. This article presents the properties of the focusing polycapillary and its performance for Fe-57 14.4 keV Mossbauer radiation using Co-57 radioactive source. The performance of the polycapillary is demonstrated with the measurement of the stainless steel. The obtained spectrum exhibited a similar signal to noise ratio as the Mossbauer spectrum acquired by using a pinhole with the diameter of 200 mu m. The usage of the polycapillary optics could be a promising way in Mossbauer spectroscopy, e.g. for measurements of tiny samples in an anvil cell.n
