Accurate Charge Density-Pendellosung Methods

Abstract

We review various Pendellosung methods for the determination of crystal structure factors. Historical matters and the methodological principles are emphasised. We also describe the current state for the case of Si. Some deformation maps based on our recent experiment (Saka and Kato 1986) are presented. It is pointed out that the real part of the anomalous dispersion term has to be determined more accurately.
