The migration energies and atomic configurations for mono- and di-interstitials and mono- and divacancies in $\ensuremath{\alpha}$ iron have been calculated using a classical model. About 530 atoms surrounding the defect were treated as individual particles, each with three degrees of freedom, while the remainder of t…

Dynamic plastic behavior of materials is influenced by internally generated temperature gradients. These gradients are a function of thermophysical properties as well as strain rate and shear strength. Criteria are presented for the prediction of catastrophic shear in materials. Catastrophic shear occurs when the loca…
Abstract The internal crystalline morphology of linear polyethylenes was examined by utilising the P ALMER ‐C OBBOLD nitric acid digestion treatment. The basically lamellar morphology reported by P ALMER and C OBBOLD was confirmed in all the cases investigated which includes extreme differences in crystallization cond…
Abstract It has been discovered that when fuming nitric acid oxidises bulk samples of polythene crystallised from the melt, preferential attack on the links between the lamellar crystals occurs with the consequent release of fragments of these crystals. The reaction is not confined to the surface of samples and lamell…
Results of absorption spectra measurements on silicate glasses of various compositions indicate that ions of the first transition-metal series are present in tetrahedral and octahedral sites in silicate melts (glasses). The fractionation patterns observed for transition-metal ions between magmas and silicate minerals…
Am Beispiel der Synthese des Nickel(II)-Komplexes des (±)-1.8.8.13.13-Pentamethyl-trans-corrins wird ein synthetischer Zugang zum Verbindungstyp der Corrine aufgezeigt. Durch die mehrfache Verwendung des Triäthyloxonium-tetrafluorborats bietet die Arbeit eine Illustration der präparativen Bedeutung der von H. Meerwein…
An exact integral equation is derived for the backscattering coefficient as a function of energy and angle. The equation has an approximate symmetry which allows one to determine the conditions under which backscattering will be independent of the energy of the incident electrons. The validity of some approximations i…
A numerical program has been developed for the calculation of atomic photoelectric differential and total cross sections, including all polarization correlations. The program is designed to calculate relativistic Coulomb wave functions in a screened central potential; the outgoing continuum wave function is obtained i…
The wave function for the electrons is investigated when a set of narrow bands (valence states) has its energies within a wide band (conduction states). The valence states are linear combinations of localized states which are attached to each lattice site. The intra-atomic Coulomb and exchange integrals for the locali…
The thermal conductivity $K$ of single crystals of silicon has been measured from 3 to 1580\ifmmode^\circ\else\textdegree\fi{}K and of single crystals of germanium from 3 to 1190\ifmmode^\circ\else\textdegree\fi{}K. These measurements have been made using a steady-state, radial heat flow apparatus for $T>300\ifmmod…
Relatively large chemical shifts in the resonance frequency of the thallium nucleus are observed in both the crystalline and molten states of different thallium salts. Relative to TlNO3, which appears to be the most ionic of all thallium salts studied, the 205Tl resonance frequency at fixed field increases in the orde…
Experimental evidence for nonradiative resonant energy transfer between Eu3+ and other trivalent rare-earth ions in Y2O3 is presented and possible interaction mechanisms are examined. It is concluded that coupling via overlap of near zone quadrupolar fields is important. Measurements on the transient behavior of the E…
