Spectrophotometric Determination of Perchlorate

Description: Technical report. Form Abstract : "Perchlorate is extracted from aqueous solution by n-butyronitrile as ferrous 1,10-phenanthroline perchlorate. The amount of perchlorate is calculated from spectrophotometric measurement of the absorbance of the extract. Moderate to large amounts of chloride, sulfate, or nitrate cause little or no interference. Chlorate is slightly extracted but the interference can be corrected."

Process Simulation on a Digital Computer Using Analog Methods

Description: Technical report. From Abstract : "A system has been developed to program a digital computer in much the same manner as an analog computer is programmed. Properties of a general purpose analog computer and a digital differential analyzer are combined to yield a program which employs, as input, standard data cards prepared from a diagram analogous to an analog computer diagram. The capacity of the system is much greater than that of most analog computers, making it applicable to large simulation… more

An Experimental Approach to a Simplified Band Structure of the Rare Earth Metals

Description: Technical report. From Abstract : "A number of the physical properties from which we can obtain both direct and indirect information concerning the band structures of metals, have been measured for most of the rare earth metals. It was thought that it would be desirable to review ans examine these data and try to tie them together. For this purpose the very low and room temperature heat capacities, Hall coefficients, magnetic susceptibilities, spectral data and electrical resistivities were exa… more

The Y-Nd and Sc-Nd Phase Systems

Description: Technical report. From Introduction : "In a recent study by Spedding, et al. on some rare earth alloy systems, an intermediate phase was found to form when a light rare earth (ABAC stacking) was alloyed with a heavy rare earth (ABAC stacking). This intermediate phase was found to have the structure of samarium metal with the stacking ABABCBCAC and was designated "delta". Since the cause of this rather unusual structure occurring in either samarium metal or these alloys is not known the study of… more

Consequent Procedures in Conventional Computers

Description: Abstract. The use of consequent procedures in designing programming systems and languages for real-time, on-line or multi-programming applications is discussed. Consequent procedures differ from normal procedures in that the flow control between procedures is defined by the consequences of the previous procedure rather than by the programmer. The use of these concepts leads to comparatively simple system and language design for general purpose systems. Interactions with the external world of h… more

A Test for Electron Transfer in the Intermetallic Compound, V4Al23

Description: Abstract: "Abnormally short interatomic distances are characteristic of aluminum-transition element compounds which occur at the aluminum-rich ends of the phase diagram." Summary: "The theoretical model assumed in this investigation was that of spherical distribution of electrons centered about atomic sites in the V4Al23 structure, represented by the theoretical scattering factors for the isolated atoms. ...It is evident from the (Fo-Fc)-synthesis maps that too much scattering power has been … more

The Mass Spectrum of Stannane

Description: From abstract: "The mass spectrum of stannane, SnH4, has been studied. Ion fragmentation patterns for both the singly and doubly charged fragments were obtained employing 70-volt electrons. From appearance potential data, an estimation of the bond energies of the tin-hydrogen bond in the ion-species SnH+3-H, SnH+2-H, SnH+-H, Sn+-H has been made along with [delta]Hf for SnH4. The studies were first made with tin of normal isotopic abundance, and then the results were corroborated with SnH4 prepa… more

Photoproduction of Beryllium-7

Description: From abstract: "The nuclide Be7 has been produced by photoactivation of Be9, B and C12 using the bremsstrahlung beam of an electron synchrotron operated at 45 Mev. Integrated cross sections for the formation of Be7 have been estimated by comparison with the Ta181([gamma],n)Ta180m reaction. The reaction C12([gamma],2p3n)Be7 has also been observed in irradiations at 30, 35 and 40 Mev maximum energy. Its yield has been compared with that of the C12([gamma],n) reaction at 45 Mev. The reaction A127(… more

Ternary Compounds Between Thorium Monocarbide and Thorium Dihydride

Description: From abstract: "The thorium-hydrogen-carbon system was studied by measuring hydrogen equilibrium pressures at various compositions and temperatures. Two compounds, ThC·ThH2 and ThC·2ThH2, were found and characterized. ThC·ThH2 has a hexagonal closest-packed lattice with ao=3.816Å and co=6.302Å. ThC·2ThH2 has a monoclinic lattice with ao=6.50Å, bo=3.80Å, co=10.91Å and β = 119°. The enthalpies of formation for each compound were determined."

Small Order Shape Factor in Na22

Description: From abstract: "The beta spectrum of Na22 has been examined using an intermediate-image beta-ray spectrometer operating at 2 1/2% transmission and 2.4% resolution. Five separate determinations of the maximum energy and of the slope of the form-factor plot were made. One determination was made using a charge-discriminating baffle inserted in the spectrometer. The unweighted mean of the five values for the maximum energy is 547.4 ± 1.0 kev. The unweighted mean of the five values for the form-fact… more

Seebeck Effect in Magnesium Silicide

Description: From abstract: "The Seebeck coefficient (thermoelectric power) has been measured from 7°K to 1000°K for both n-type and p-type single crystals of Mg2Si...The phonon contribution, Sp, was obtained from the measured Seebeck coefficient by subtracting off the electron diffusion term, Se, which was calculated with the aid of the measured Hall coefficient. The magnitude of Sp was observed to be proportional to T-3 and to show the dependence on sample size and on carrier concentration predicted by th… more

Point Imperfections in Metals: Existance and Detection

Description: From introductory paragraph: "The factors which control the properties, and hence the utility, of an alloy are microscopic in nature. These factors are controlled by controlling the composition and past history of the material. control of the composition of the alloy determines for the most part the number and types of phases which will be present, while control of the past history of the alloy determines the grain size and degree of crystalline perfection within the grains. Since the electrica… more

Internal Conversion Coefficients of the 2+-0+, E2 Transitions in Even-Even Sm152[over]90 and Gd152[over]88

Description: From abstract: "To investigate the deviation of the internal conversion coefficients of E2 transitions from theoretical computations and their dependence on nuclear deformation, the total internal conversion coefficient of the 121.8-kev 2+-0+ transition in ellipsoidal Sm152[over]90 was measured to be 1.135 ± 0.010 with a high accuracy coincidence-sum method.

gem-Bis(disubstitutedphosphinyl)alkanes. II. Extraction Properties of Bis(di-n-hexlphosphinyl)methane

Description: From abstract: "Bis(di-n-hexylphosphinyl)methane, HDPM, [(C6H13)2P(O)]2CH2, has been studied as an extractant for a variety of metals. HDPM was evaluated as an extractant for uranium(VI) and compared with tri-n-octylphosphine oxide, TOPO, (C8H13)3PO. In nonpolar solvents, HDPM forms a polymeric-like substance with compounds of uranium(VI). Viscosity measurements indicate that the molecular weight of this polymeric-like substance is about 100 times greater than the corresponding complex with TOP… more

Transport Reactions of Vanadium(III) Halides and Bromine

Description: From introduction: "...This investigation was originated to explore the possibility of vapor transport of VCl3 by chemical reaction. The reaction first considered was that of VCl3 and bromine which gave a rapid vapor transport of VCl3. Other work on solid solution formation in the system VCl3-VBr3 and transport of VBr3 in bromine developed thereafter."

Pyrometallurgical Reprocessing of Thorium-Uranium Fuel

Description: From summary: "A proposed metallurgical procedure for reporocessing Th-U233 fuel has been outlined. Some basic experimental data pertinent to the proposed process which has been published elsewhere has been reviewed and some new data presented. In the dissolution of thorium-uranium alloy in magnesium the data show that protactinium precipitates with the uranium and cerium remains in the magnesium-rich solution. It is expected that yttrium, other light rare earth elements, the alkali and alkalin… more
