The EXAFS measurement needs to disperse the incident X-ray beam with monochro-mating crystal. Beside the. continuous and some characteristic spectrum from nonsynch-rotron radiation, "negative peak" sometimes occur. It will distort the signal desired. This paper reports the detailed investigation of the "negative peak" and the interpretation with X-ray multiple diffraction. Fially, the method to avoid it is discussed.
