In a previous communication (Rooksby, 1943) it was reported that critical examination of X-ray powder photographs of nickel oxide disclosed a departure of the crystal structure from cubic symmetry.

The Laplacian probability equation can be used to predict the reproducibility of the intensities of x-rays diffracted by crystalline powders. If absorption is neglected, and N is the number of particles irradiated, p the proportion of particles which are oriented so as to diffract, and q=1 − p, the relative mean devia…
We have developed a method for the evaporation of alloys in high vacuum which from the nature of the procedure used should be applicable to all alloys which are not refractory. The method has been tested on α-brass and β-brass and on a gold-cadmium alloy. These alloys have components whose vapor pressures are very dif…
Abstract The influence has been studied of systematic alterations in the amount of cross linking in elastomers upon diffusion coefficients and permeability constants in elastomers of homologous paraffin hydrocarbons. In a number of such media the influence of chain length of the paraffins upon the transport phenomena…
The heat of sublimation of graphite and the heats of dissociation of CO and C2, which have been the subject of much controversy in recent years, have been unambiguously established by the direct determination of the total vapor pressure of graphite by an equilibrium effusion method and by the determination of the part…
Recently a number of authors have discussed the theory of critical phenomena in magnetic ma-terials and produced results differing from the con-ventional and simple theory as described in many
Abstract The calculations presented are an extension of the work of Bashforth & Adams (1883) to give the shapes of pendant drops of liquids for values of β from — 0.25 to — 0.6 at intervals of 0.025. The results have been used to calculate, to an accuracy of 0.001 to 0.01 %, the constants needed for measuring surf…
Abstract The crystal structure of diamond was first determined by Bragg in 1913 from X-ray photographs; the carbon atoms are arranged at the apices and median points of interlinked tetrahedra. Born (1914) derived expressions for the three elastic constants of diamond in terms of two force constants related to the vale…

The secondary emission electron multiplier is chosen to illustrate the phenomenon of ‘cascade multiplication’. A method is given for deriving the semi-invariants of the probability distribution for the number of output electrons after any number of identical stages of multiplication, in terms of the corresponding semi…

A bstract Some evidence leading to the supposition that certain borosilicate glasses containing a high percentage of silica are made up of two‐component glasses is presented. One of these components, which consists mainly of silica and has a low expansivity, forms a rigid network throughout the body of the glass while…
Abstract Da das magnetische Moment der Elektronen mit einem mechanischen Drehimpuls verknüpft ist, muß die Verteilung der Magnetisierungsvektoren in einer bewegten Wand zwischen zwei Weißschen Bezirken sich von derjenigen in der gleichen Wand in Ruhe etwas unterscheiden. Der Energieinhalt der bewegten Wand ist deshalb…
