Title: Structural analysis by reduced data: VII. Experimental check of the new method for refining the parameters of the model describing the absorption of radiation by a specimen

Abstract

A new approach to refinement of the parameters determining the absorption of radiation by a single-crystal specimen is used to refine the structural models of three ellipsoidal crystals and a polyhedral crystal. The use of this approach significantly increased the relative precision of the structural results. In three cases, this method made it possible to improve the models qualitatively. The effect of correlations between the parameters describing the specimen shape and the parameters of other anisotropic effects is considered. The high sensitivity of the method is demonstrated by the example of a low-absorption specimen ({mu}R {approx} 0.12)
