Loss of symmetry of local environment of tin atoms in Pb1-xSnxTe crystal lattice

Splitting of Mossbauer spectra of 119Sn nuclei has been observed in the narrowband semiconductors Pb!_xSnxTe. This indicates that the tin atoms go over into a position with a lower than cubic symmetry of the local environment.
