Influence of the Bonding Electrons on the Scattering of X-Rays by Carbon

Naturevolume 165pages7172 (1950) | Download Citation



DURING the course of an investigation of the scattering of X-rays by Various carbons (incompletely graphitized materials containing graphite-like layer-planes but no three-dimensional crystalline order, and showing, therefore, only (00l) crystalline reflexions and (hk) two-dimensional bands) it was observed that the intensity of the (10) band was always anomalously high. The phenomenon was found to be of perfectly general occurrence for a wide variety of carbons. For microcrystalline graphite a similar anomaly was observed in the intensity of the (100) line. Moreover, examination of intensity curves published by other authors1 confirms the generality of the phenomenon.
