Abstract
119Sn Mössbauer emission spectroscopy data demonstrate that the impurity tin atoms resulting from the radioactive decay of the 119Sb isotope in the structure of glassy As x S1 − x and As x Se1 − x alloys reside on the arsenic site and act as two-electron amphoteric centers with a negative correlation energy: tetravalent six-coordinate tin acts as a singly ionized donor, and divalent three-coordinate tin, as a singly ionized acceptor.
