Extended x-ray absorption fine structure (EXAFS) measurements were made on a-Ge and a-Ge:H films which were prepared by sputtering and were annealed at temperatures between 300 and 450° C.The first nearest neighbor distance and the Debye-valler factor were investigated. These values decrease rapidly on the crystallization of the samples. The relationship between them was analyzed in respect of tvo-body potential. The potential of amorphous state is considered to be affected by unharmonic term.
