The Mössbauer Effect of Sn119 in Palladium-Rich Palladium—Tin Solid Solutions
Until quite recently the Mössbauer spectroscopy of tin has been hindered by the lack of a high-effect, narrow Sn119m source. The first tin Mössbauer source to be used widely was stannic oxide, Sn119mO2. Although the Mössbauer absorption spectrum of SnO2 shows a satisfactory effect at room temperature, its width is excessively large because the peak is a doublet . In terms of line width the Mg2Sn119m source reported by Ruby and Flinn  is far superior to stannic oxide. This source, however, has a negligible effect at room temperature and therefore must be used at temperatures below 77°K.
