The information about the atomic arrangement (radial distribution function, pair correlation function etc.) is obtained by means of radial distribution analysis using X-ray. However, the scaling of the data to the atomic scattering factor becomes difficult when the observed halo pattern include background because the X-ray used in the measurement is not fully monochromatic. In this report, we discuss the analytical determination of the background and the scaling factor by reproducing both halo pattern and atomic scattering factor by means of modified exponential function (mef=K-AB^S) when the background is included in the observed halo pattern. At first, we discuss the validity of using modified exponential function to reproduce both the halo pattern and the atomic scattering factor, and next the influence of the procedure on the radial distribution function.
