The Physical Meanings of 5 Basic parameters for an X-Ray Diffraction Peak and Their Application
2003
This paper derives the physical meanings of peak position, peak width and height ofan X-ray diffraction peak from the analyses of the Bragg's equation, the Scherrer' s formula andthe principle of peak intensity calculation. The geometric characteristics of an asymmetric peakare clarified by means of experiment. The relationships between neak shape and domain size/lattice strain have been verified by geological events. Therefore this paper integrates the physicalmeanings of all 5 basic parameters for an X-ray diffraction peak. Applications of these 5 parame-ters are exemplified.
