Impurity {sup 119m}Sn atoms arising as a result of radioactive decay of parent {sup 119mm}Sn atoms in the structure of the glasses As{sub 2}S{sub 3}, As{sub 2}Se{sub 3}, and As{sub 2}Te{sub 3} are part of the glass composition in the form of structural units corresponding to tetravalent tin. The impurity {sup 119m}Sn atoms formed as a result of radioactive decay of {sup 119}Sb atoms in the structure of the As{sub 2}S{sub 3} and As{sub 2}Se{sub 3} glasses are localized at the arsenic sites and play the role of two-electron centers with a negative correlation energy. For the As{sub 2}Te{sub 3} glass, similarly formed {sup 119m}Sn atoms are electrically inactive. The greatest part of the daughter {sup 119m}Sn atoms arising after radioactive decay of parent {sup 119m}Te atoms are located at the chalcogen sites and are electrically inactive in the As{sub 2}S{sub 3}, As{sub 2}Se{sub 3}, and As{sub 2}Te{sub 3} glasses. A significant recoil energy of daughter atoms in the case of the {sup 119m}Te radioactive decay brings about the appearance of the {sup 119m}Sn displaced atoms.
