Gamma-ray resonance fluorescence

Although more than 50 nuclei are known for which gamma-ray resonance fluorescence (the Mossbauer effect) has been observed,1 the present contribution will concern itself primarily with data pertinent to experiments using the 14.4 keV radiation of s7Fe and the 23.8 keV radiation of ll9Sn, since the vast majority of studies related to chemical structure problems have exploited these two nuclides.
