An EXAFS investigation has been made at both the Ge and the Se K edges to compare the crystalline and amorphous states of the germanium diselenide GeSe{sub 2}. Special care was taken during sample preparation and it has been possible to analyze the second shell of neighbors which surround germanium. The differences between the specimens are analyzed in terms of a depolymerization factor and related to a clustering process.
