Abstract Neutron powder diffraction patterns are measured at 50°C and liquid nitrogen temperature. The crystal structure is defined as D8 8 (space group P6 3 /mcm), in agreement with CASTELLIZ 's data [2]. It is found that the atoms in the 4 (d) and 6 (g) positions have magnetic moments of (3 ± 0.1) and (2 ± 0.1) Bohr…
Melting relations in the systems CaO‐manganese oxide and MgO‐manganese oxide in air have been determined at temperatures up to 1705°C. In the system CaO‐manganese oxide four crystalline phases have stable existence in equilibrium with liquids: lime (approximate composition CaO‐MnO), spinel (approximate composition Mn…
It has been demonstrated that the use of solvent additives can substantially increase the rate of radiation-induced graft polymerization in the systems polyethylene–styrene, polypropylene–styrene, polyvinyl chloride–styrene, nylon–styrene, polyethylenemethyl acrylate, polypropylene–methyl acrylate, nylon–methyl acryla…
The mean free paths and attenuation lengths of hot electrons and holes in metals are calculated by Morte Cario methods. The results are compared with experimental results for electrons in Au,-Ag, Cu, and Pd and holes in Au. (T.F.H.)

The cations Na, K, NH4, Ca, Mg, Mn, and, in certain instances, Ba, Sr, and Pb combine with the anion SO4 to form 58 mineral species. Slightly more than half are hydrous, and several contain Cl, F, or CO3. Infrared absorption spectra of most of the above sulfate s have been obtained with a split beam infrared spectroph…

The values of the upper yield, the lower yield and the flow stresses of polycrystalline Armco iron are shown to have very similar dependences on temperature between 78°K and 200°K. The variation with temperature of the component of the upper and lower yield stresses which is associated with the unpinning of locked dis…
A wide range of compositions of the title system have been prepared with x ranging from 0.10 to 0.99, and x‐ray parameters and pertinent thermoelectric properties such as Seebeck coefficient, electrical resistivity, and thermal conductivity were determined. Particular emphasis was given to the range of x from 0.95 to…
A method for obtaining extremely wide-band light modulation by traveling-wave interaction in electro-optic or magneto-optic materials is described. When the intrinsic velocity of microwaves in the material is appreciably less than that of light, the synchronism conditions require the light to be directed obliquely wit…

An oxide of titanium, apparently Ti 2 O 3 , showed solid solubility in Al 2 O 3 of 1.0, 1.8, and 2.5 mole % at 1400°, 1600°, and 1700°C, respectively, when heated in hydrogen with a dew point of about ‐50°C. At the same temperatures in air, however, no indication of solid solubility (of TiO 2 , presumably) was found b…

Films produced on titanium depend on the nature and concentration of electrolyte, forming voltage, current density, and temperature. In most cases, dense films of limited thickness are produced, but in some cases, thick, porous films result. Physical, chemical, and electrical nature of the coatings are discussed toget…
The zirconium-deuterium system in addition to α-Zr consists of three deuteride phases: γ, δ, and ε. Each phase exists over a wide range of compositions. The γ phase is tetragonal. The δ phase is cubic (CaF 2 -type). The ε phase is tetragonal. Its lattice constants vary with composition as it approaches stoichiometry o…
