Abstract
We investigated the dependence of Lotgering factor variation on crystal structure of a material. The resultant XRD pattern of the material from its crystal structure is key point to determine the variation of Lotgering factor. The linkage of the Lotgering factor and distribution for crystallographic orientation was accomplished by using a parameter r of March-Dollase function as a distribution of orientation. This linkage clarified that materials belonging to the same category of crystal structure results in the similar variation of Lotgering factor.
