Local symmetry and electronic structure of atoms in the Pb_(1-x)Sn_xTe lattices in the gapless state

摘要

Moessbauer spectroscopy on the ~(67)Ga(~(67)Zn), ~(119)Sn and ~(129m)Te(~(129)I) isotopes has shown that no modifications of the local symmetry of lattice sites, electronic structure of atoms and intensity of electron-phonon interaction are revealed for Pb_(1-x)Sn_xTe solid solutions in the gapless state at 80 and 295 K.
