摘要：

An analytical approach for locating the absorption edges based on Fourier transformation of EXAFS data is presented.The chemical shifts of the absorption edges between RE metals and their oxides calculated using this approach give more accurate results as it eliminates the uncertainty in the location of absorption edges.
