TL;DR: In this article, the intrinsic stacking fault density (α) has been calculated from X-ray peak shift measurements on filings of solid solutions based on Cu, Ag and Ni and on Pb and Al, respectively at room temperature and in liquid air.

TL;DR: In this paper, the quantum-mechanical interpretation of vanadyl bond in transition groups was studied and the properties of the initial elements from transition groups were investigated, such as titanium, vanadium, zirconium, niobium, hafnium, tantalum and tungsten.
Abstract: Elements such as titanium, vanadium, zirconium, niobium, hafnium, tantalum, and to some extent molybdenum and tungsten cannot be seen in their common valency states by the electron paramagnetic method; all other valency states of these elements are paramagnetic. A special study should be made of the quantum-mechanical interpretation of vanadyl bond in these minerals; of the crystallochemistry of compounds with a vanadyl bond; of their optical and infrared spectra; and of all compounds of the initial elements from transition groups. — IGR Staff.

TL;DR: In this article, the authors used one-electron hydrogen-like functions and Slater screening contants to predict the Β-decay of all the valency states of the elements from Li to Kr.
Abstract: Excitation and ionization probabilities consequent on Β-decay are shown to be predicted satisfactorily for the elements from Li to Kr by the use of one-electron hydrogen-like functions and Slater screening contants. Numerical calculations are presented for the Β-decay of all the valency states of the elements from Li to Kr.

TL;DR: A simple charge compensation mechanism for the substitution of mixed valency ions in oxide crystals requires a fixed ratio of the substituents in the melt to obtain equal concentrations of the substitution in the solid, or balanced substitution.
Abstract: A simple charge compensation mechanism for the substitution of mixed valency ions in oxide crystals requires a fixed ratio of the substituents in the melt to obtain equal concentrations of the substituents in the solid, or balanced substitution. A direct relationship between the melt concentration ratios and the deviation from balanced substitution has been deduced from the theory and shown to hold in practice for the substitution of chromium and lithium in zinc tungstate. This relationship permits the required ratio for balanced substitution to be obtained directly from limited experimental data.
