The Coefficient of Thermal Expansion of Magnesium Oxide
The thermal expansion of single crystal magnesium oxide has been measured from 85°K to 480°K. The results are combined with those of Austin, so that data are available from 85°K to 1273°K. The observed thermal expansion of this substance is in excellent accord with the relation, due to Grüneisen, between thermal expan…

Note on Absolute Multiplet Strengths
A table of factors is given by means of which the relative multiplet strengths tabu- lated by the writer in an earlier paper may be converted to absolute strengths in terms of c2, the square of the one-electron matrix component. ~ is a constant for any given tran- sition array

The Ferromagnetism of Nickel. II. Temperature Effects
With the model proposed in an earlier paper, the temperature variation of the ferromagnetism of nickel is discussed. By application of Fermi statistics to the electrons in the $d$ bands, the free energy is computed as a function of temperature and magnetic moment. At each temperature, the value of magnetic moment for…
Variation of Resistance and Structure of Cobalt with Temperature and a Discussion of Its Photoelectric Emission
X-ray (Hull-Debye-Scherrer) diffraction patterns were obtained for cobalt in a camera designed for high temperature work. No crystallographic change for this metal has been observed in the region about 850\ifmmode^\circ\else\textdegree\fi{}C at which the change in the photoelectric emission has been reported. The $\en…
Heat Capacity, Entropy, and Free Energy of Rubber Hydrocarbon
Abstract The best method for obtaining the free energy of formation of rubber is by making use of the third law of thermodynamics. This makes necessary the determination of heat-capacity values of rubber from room temperature down to temperatures sufficiently low to apply an empirical formula for obtaining the values…
The Application of the Three-Dimensional Patterson Method and the Crystal Structures of Proustite, Ag3AsS3, and Pyrargyrite, Ag3SbS3
It is shown that the three-dimensional Patterson method can be so simplified by the use of the symmetry properties of the crystal under consideration that its use in determining the positions of atoms in crystals is practicable. This method is then used to determine the positions of the heavy atoms in proustite, Ag3As…
THE DOUBLE REFRACTION OF CHITIN
The double refraction of the chitinous hair of the crayfish is positive with respect to the axis of the hair, and is largely caused by the arrangement of submicroscopic, elongated chitin particles parallel to this axis (form birefringence). Using a series of relatively unreactive liquids and fluid mixtures which perme…
A Note on the Possible Effect of Screening in the Theory of Beta-Disintegration
The present paper considers the possibility that screening by the atomic electrons has an appreciable effect on the energy distribution of $\ensuremath{\beta}$-particles emitted by heavy nuclei. A general formula is derived from which it is possible to conclude that the effect of screening is negligible. This result i…

The Crystal Structure of Silver Phosphate
A new value for the oxygen parameter in the structure of silver phosphate has been determined which gives the P–O separation in the phosphate group as 1.61A±0.03A. The value found here is slightly larger than that determined from an analysis of the crystal KH2PO4. The slight increase in P–O distance is explained on th…
