A calculation of γ(r), the correlation function which gives the X-ray scattering of a cubic object of uniform density, is given for the full range of r. A new method, which can be applied to other systems, is used. The function γ(r) and its first derivative are everywhere continuous, but γ′′(r) is discontinuous at r =…

Coordination polyhedra in crystals are identified by matching interbond angle matrices for observed and ideal polyhedra. An algorithm for permuting the N vertices of the observed polyhedron is described in which not all of the N! combinations are examined. The method has been used to identify a number of higher-coordi…

The effect of two-magnon-one-phonon scattering processes on the lattice thermal conductivity of antiferromagnets is studied. Transition matrix elements are obtained by expansion in lattice displacements of the exchange and anisotropy for an anisotropic Heisenberg Hamiltonian. Relaxation times for the phonons are deter…

The thermal decomposition of solid PVC was studied in the presence of added hydrogen chloride and hydrogen bromide over the temperature range 170–210°C. Under certain conditions the decomposition was shown to be dependent in a first-order manner on the hydrogen halide pressure. These gases acted as catalysts, increasi…

Abstract The crystallization behavior of high density polyethylene/isotactic polypropylene blends (HDPE/PP) was investigated. The overall kinetics of crystallization of HDPE may be strongly influenced by the addition of a small fraction of PP. At 398 K the half crystallization time of the blend containing 10% by weigh…

The transformation of graphite to diamond by impact-produced shock waves has been examined using a gas gun to launch projectiles onto graphite and a graphite-metal mixture. Analysis of the mechanism of transformation is complicated by the post shock graphitization of most of the diamond produced. It is argued that the…
