Abstract
The Green's function technique has been studied in detail, permitting numerical calculations of mean-square amplitudes in perfect and impure lattices. The 119Sn substitutional atom is distinguished by being an isovalent impurity in Si, Ge and α-Sn, and by being an amphoteric dopant in the III-V semiconductors. Several impurity models are employed for quantitative interpretation of Mössbauer Debye-Waller factors from a systematic study by Weyer et al.
