Only with the advent of four-circle diffractometers and high-speed computing could sufficiently accurate data be collected, corrected for physical effects like extincti

The condition that a 1-density matrix come from a wave function is ensured by requiring that its eigen-values fall in the range between zero and one. A particular case we have studied because it is a most important fi

It is applied to the bond properties of some diatomics where relativity plays a major role, among other things giving a new explanation for relativistic bondlength contractions. Relativistic effects in photoelectron spectra are studied. Finally the changes in the molecular electron den

The calculated charge densities result from self-consistent energy band calculations for these crystals using the method of linear combination of Gaussian orbitals (LCGO), with a local density form of exchange-correlation potential. The calculations are fully . w

,Hilfsbuch für den Apparatebau, we are to thoroughly understand the nature of the earth’s materials and the physical and chemical state of the earth’s interior. From a chemical point of view, perhaps the most basic property of a silicate mineral is its charge density distribution. An accurate knowledge of this distribution may pr

There is in this study no evidence for the participation of calcium in a pattern of directed bonding and its primary role may be in charge stab
