A method has been devised for calculating the absorption factor for the powder method. It may be used for all values of μ r , where μ is the linear absorption coefficient and r the radius of the specimen. It is, however, especially suitable when μ r exceeds 2. For smaller values of μ r , for which the calculations are…

γ-Fe2O3. γ-Al2O3 and the oxide obtained by the electrolytical oxydation of Al (γ′-Al2O3) are averaged structures with regard to the cations. Both the γ and γ′ oxides have the same oxygen-lattice but there is a distinct difference in the degree of incomplete arrangement of the cations. γ′-Al2O3 and γ-Al2O3 (Fe2O3) are…
The changes that occur in the magnetic properties of iron-cobalt-nickel alloys when they are annealed in a magnetic field, have been investigated for a series of these alloys. The maximum change for the iron-nickel alloys occurs between 65 and 70 percent nickel and is evidenced by a large increase in maximum permeabil…
The lattice-dimensions of pure zinc oxide condensed from the smoke have been determined to a high degree of accuracy by means of X-ray powder photographs. Bradley and Jay's lattice-dimensions of quartz and Siegbahn's X-ray wave-lengths being accepted as standards, the lattice-dimensions of zinc oxide are found to be:…
The method of Wigner, Seitz and Slater has been applied to the determination of the electronic structure of diamond. It is found that the energy levels of the carbon atom are broadened into bands similar to the energy bands in metals. The 2s level of the atom splits into two bands, and the 2p level into six bands. The…
The problem of accounting for the anomalous scattering of gamma-rays suggests the importance of investigating the probability of processes in which an incoming quantum produces an electron-positron pair in the field of a nucleus, going on in a new direction with diminished energy. To determine the cross section in the…

Abstract "Bleaching powder" is made by the action of chloride gas on calcium hydroxide, the reaction being essentially: 2Ca(OH)2 + 2Cl2 → Ca(OCl)2 + CaCl2 + 2H2O. The constitution of the solid formed in this way has been the subject of investigation and speculation for many years, since its properties are not those to…

Kaolinite was synthesized by heating coprecipitated AJ20 3-Si02 gels and mixtures of Al20 3 and Si02 with water in a pressure bomb at 310 0 C. Similarly dickite was prepared by treating coprecipitated Ah03-Si02 gels at 350 0 C and 365 0 C, beidellite from mixtures of Ab03 and Si02 at 350 0 C and 390 0 C, and also from…

A comparison of Fermi's formula for the distribution in energy of the electrons and positrons emitted by radioactive bodies with the observed spectra seems to show that a basic factor in it, the statistical factor, is not asymmetric enough. Since about the same degree of asymmetry is common to the spectra of light and…
The magnetic susceptibilities and electrical conductivities of cobalt, nickel and palladium and of their alloys with copper, silver and gold are discussed on the basis of the quantum theory of metals. It is shown that the number of electrons in the outermost s state must be about 0.6 per atom in the transition metals…

Some of the consequences of the positron theory for the special case of impressed electrostatic fields are investigated. By imposing a restriction only on the maximum value of the field intensity, which must always be assumed much smaller than a certain critical value, but with no restrictions on the variation of this…
Abstract In a recent paper, Bragg and Williams have pointed out that the arrangement of the atoms in an alloy depends in a striking way on the temperature. At high temperatures, the atoms are distributed practically at random among the lattice points of the crystal, but at low temperatures a superlattice may be formed…
The theory of Ewald and Born of the double refraction of crystals is applied to the calculation of the photoelastic properties of $D$ lattices. Only in special cases, as for instance in KCl for pressure parallel [111], is the effect determined by the anisotropy of the Lorentz and Coulomb forces. In these cases the pho…
