✦ Synopsis

The computational method of EXAFS amplitude correction by harmonic elimination has been worked out. In conventional absorption measurements the major source of errors is the transition of harmonics by the monochromator. In this paper we present the effective correction method based on the measurements of the intensity of the X-ray radiation penetrated through calibrated metal foils both without and together with investigated samples. As an advantage of the method one may emphasize a fact that it does not require any additional data for investigated samples such as chemical composition, density, table absorption coefficients needed for existing methods.
