摘要：

Mossbauer spectroscopy was used for the early stage detection of the beta -> alpha transition (tin pest) in Sn matrix. The results were compared with the data from X-ray diffraction and a variance in the sensitivity for both methods has been proven. Mossbauer spectroscopy is more responsive method than XRD to tin pest finding and with possible detection level of even 1.8%. Furthermore, in reference sample, suspected to be pure alpha-Sn, large content of white tin (beta-Sn), even after 6 years of exposure at sub-zero temperature, has been identified. 48% of alpha-Sn phase but also 52% of non-transferred beta-Sn has been still detectable.
