Charge distribution and energy levels of trapped electrons in ionic solids

J. Simpson1949-06-07Proceedings of the Royal Society of London A Mathematical and Physical Sciences

Abstract The charge distribution and energy levels of electrons trapped at two types of lattice defect in ionic solids (interstitial ions and F-centres) are calculated using a variation method which takes account of the fact that the field acting on the electron near such a defect depends upon the wave function of the…

Crystal growth from solution

S. P. F. Humphreys-Owen1949-06-07Proceedings of the Royal Society of London A Mathematical and Physical Sciences

Abstract Single crystals of the cubic form of sodium chlorate are studied in growth from aqueous solution. An interferometric technique measures, via refractive index, concentrations and gradients of concentration contiguous to the crystal. The rates of advance of individual faces are measured and compared with predic…

The crystal structure of atacamite and the crystal chemistry of cupric compounds

A. F. Wells1949-06-02Acta Crystallographica

The co-ordinates assigned in an earlier study of the crystal structure of atacamite, Cu2Cl(OH)3 or CuCl2.3Cu(OH)2, have been revised. Each Cu atom is shown to have four nearest OH neighbours (mean Cu—OH distance 2.01 A.), and in addition two more neighbours completing distorted octahedral co-ordination groups. For one…
