Abstract
The 119mSn impurity atoms formed as a result of the radioactive transformation of the 119mmSn parent atoms in the structure of glasses in the As-S and As-Se systems and the As2Te3 glass are involved in the glass composition in the form of Sn4+ ions. The 119mSn impurity atoms formed after the radioactive decay of the 119Sb atoms in the structure of glasses in the As-S and As-Se systems are located in the arsenic sites and play the role of two-electron centers with a negative correlation energy. For the As2Te3 glass, the 119mSn atoms formed in a similar manner are electrically inactive. The larger part of the 119mSn daughter atoms, which are formed after the radioactive decay of the 119mTe parent atoms in glasses of the As-S and As-Se systems and in the As2Te3 glass, are located in the chalcogen sites and are electrically inactive. The significant recoil energy of the daughter atoms in the case of decay of the 119mTe atoms leads to the appearance of displaced 119mSn atoms.
