摘要：
A simplified analysis of extended X-ray absorption fine structure (EXAFS) data has been presented for copper and nickel metals. Theoretical EXAFS data has been generated using standard EXAFS equation employing the software Mathcad. The phase shift for the backscattered photoelectron wave has been obtained from the experimental data itself. The backscattering amplitude taken from the available tabulations and other parameters taken from crystallographic data have been used as input to the EXAFS equation. The theoretical EXAFS data and its Fourier transform agree well with the experimental results. The bond length obtained for the first coordination shell compares well with the crystallographic value.
