Splashes from underwater explosions
Abstract The splashes from the underwater explosions of 1 and 10 lb. charges of P.E. no. 2 and Nobel’s Explosive ‘808’ at various depths have been photographed with cine-cameras. The experiments were carried out in a sheltered pond which enabled the surface phenomena to be studied in greater detail than has been done…
Neutron Diffraction Studies of Order-Disorder in Alloys
Neutron diffraction techniques have been used to study order in the substitutional solid solutions FeCo, ${\mathrm{Ni}}_{3}$Mn, and ${\mathrm{Cu}}_{3}$Au. Superlattice effects have been found in the first two examples, which are difficult to study by x-rays.
CRYSTALLOGRAPHIC INVERSIONS OF THE ALUMINUM ORTHOPHOSPHATE POLYMORPHS AND THEIR RELATION TO THOSE OF SILICA*
A bstract The temperature‐stability relationships of the AlPO, polyrnorphs have been studied by X ray, thermal analysis, and thermal expansion. The system parallels that of silica very closely. Following is a diagrammatic representation of the findings for AlPO 4 : Conversions from one form to another are shown to be…
Degree of lateral order in various rayons as deduced from x‐ray measurements
Abstract X‐ray measurements on 16 different specimens of regenerated cellulose reveals that there exists a pronounced negative correlation between the integrated intensity of the 101 interference and its halfwidth. The 101 plane is a preferred cleavage plane and represents the lamellar plane of the ribbon‐shaped cryst…
The X-ray measurement of the amorphous content of polythene samples
A method is described for the determination of the amorphous content of polythene samples, based on a microphotometric comparison of the intensities of the amorphous band and the two strongest crystalline lines on X-ray powder photographs obtained from the samples in sheet form. Corrections for two types of orientatio…

X‐ray studies on the crystallinity of cellulose
Abstract The method for the evaluation of the percentage crystallinity in cellulose preparations from x‐ray intensity measurements, previously described in detail (J. Appl. Phys., in press) is reviewed briefly and new material presented consisting of crystallinity percentages between 8% and 70%. Cotton, flax, and rami…
The accuracy of electron-density maps in X-ray analysis with special reference to dibenzyl
Methods of correcting the systematic errors in electron-density maps due to using finite series of structure factors are discussed. Random errors in the maps are caused by experimental and computational rounding-off errors and by errors in the correction for finite series. Expressions are derived for the standard devi…
