Average Fission Cross Section U238 for Fission Neutrons

Description: By means of measurements with a double ionization chamber, the average fission cross section of U238 for neutrons from the fission of U235 was determined in terms of v, the average number of neutrons per fission of U235. the number of fission of U238 was measured in one of the ionization chambers while the number of fissions from the fission neutron source of U235 was measured in the other chamber. In the nine runs made to determine the cross section, a variety of different methods was used to … more

Crystal Structure of a KPuO₂CO₃, NH₄ PuO₂CO₃, RbAmO₂CO₃

Description: From abstract: "The preceding article describes the preparation of a number of alkali carbonates of pentavalent neptunium, plutonium, or americium. The results of x-ray diffraction studies of some of these carbonate precipitates are presented in the present paper. The preparations to be dealt with are the K-Pu(V) (at low pH), NH4-Pu(V) and Rb-Am(V) precipitates which form one iso-structural series. In the case of the other preparations discussed in the preceding article, the x-ray work did not … more

Density and Refractive Index of Uranyl Fluoride Solutions

Description: "In the course of an ultracentrifugal investigation of uranyl fluoride solutions, their densities and refractive indices were measured as a function of concentration. The measurements were carried out near 25 and 30 C and if necessary extrapolated to 25.0 and 30.0 C from the observed temperature coefficients. Most density data were obtained pycnometrically (25 cc samples) and a few gradient tubes. The refractive index measurements were carried out with a Bausch and Lomb dipping refractometer (c… more

An Experimental Method to Determine Equation of State Data for Solids by Shock Wave Measurements

Description: The following report describes and experimental method used to determine equation of state of materials under strong shock. The method was devised of simultaneously measuring the velocity of the shock through a plate, and the velocity of the free surface after the shock has traversed the plate. Further analysis is presented.

General and Engineering Geology of the Wray Area, Colorado and Nebraska

Description: From abstract: Most of the formations in the Wray area are fair foundation materials, although good construction materials are scarce. The gravel of the Grand Island formation and the gravels in the Ogallala formation contain large quantities of clay, silt, sand, and calcium carbonate, and have very few pebbles larger than one-half inch in diameter.

Geology of Carnotite-Bearing Sandstone in the Uravan and Gateway Districts, Montrose and Mesa Counties, Colorado, and Grand County, Utah

Description: From Introduction: "In the Uravan and Gateway districts, the general character of the bedding in the ore-bearing sandstone and amount of alteration in associated mudstones, and the relation of these to each other, are the features most useful as large-scale guides. This report describes these features and their distribution, as well as some other significant geologic characteristics of the ore-bearing sandstone."

Knob Creek Monazite Placer, Cleveland County, North Carolina

Description: From abstract: The area comprising the first flood plain downstream from the headwaters of Knob Creek was one of three monazite placer deposits near Shelby, N. C., recommended by the Geological Survey for investigation by the Bureau of Mines as a joint effort by the above two agencies. Past production of monazite from the headwaters of this stream and its drainage of an area of known source rocks were factors influencing this selection. Drilling of the deposit was started on November 26, 1951, … more
