ACCEPTOR DOPANTS FOR LEAD TELLURIDE

Description: Alternative P-type dopants such as, Th, P, and As were studied. Ingots were grown from a melt containing one at.% dopant and their electrical properties evaluated. Also, sintered pellets of PbTe were doped by exposure at high temperature to gaseous dopants. In most cases, the doping concentrations obtained were insufficient for SNAP 10A requirements. In the case of As, however, doping of Te-rich PbTe, the desired heavy doping was obtained. These preliminary studies suggest that dopants other th… more

Adsorption of Krypton and Xenon by Various Materials

Description: The adsorptive capacities of various inorganic adsorbents and activated charcoals for krypton and xenon were determined. Columbia-G activated charcoal had the highest capacity for both krypton and xenon at pressures from 0.01 to 125 mm Hg and temperaturens from 2 to 85 deg C. If a value of 1 is assigned to the capacity of this charcoal at 28 deg C for krypton, other charcoals range from 0.63 to 0.84, molecular sieves (except 4A) from 0.11 to 0.20, and some silica genls from 0.05 to 0.07. Variou… more

Biological Effects of Blast. Technical Progress Report

Description: The current state of knowledge relevant to biological blast effects was summarized in a selective manner. Initially, five problems of concern to those who would relate the environmental variations produced by nuclear weapons with biological response and hazard assessment were pointed out. Primary, secondary, tertiary, and miscellaneous blast effects were defined and selected interspecies experimental data of a physical and pathophysiological nature useful in estimating human response were prese… more

Critical Experiments With Thoria-Urania Fuel In Heavy Water

Description: The nuclear characteristics of a variety of small reactors composed of thoria -urania fuel in heavy water were determined in a program of critical experimentation. The fuel element consisted of ceramic ThO/sub 2/-U/sup 235/ O/ sub 2/ pellets stacked to a height of 1.5 m within 0.787-cm-OD aluminum tubing. The pellets used most frequently were of 0.587-cm diameter and had a Th/U/sup 235/ atom ratio of 25. Rods containing similar pellets with only half as much U/sup 235/ were used to achieve smal… more

Heat Transfer With Laminar Flow in Concentric Annuli With Constant and Arbitrary Variable Axial Wall Temperature

Description: An analysis has been performed to determine the heat transfer characteristics for laminar forced-convection flow in a concentric annulus with prescribed surface temperatures. Three distinct problems were considered: (a) wall temperature prescribed at both the inside and outside wall; (b) inside wall temperature prescribed and the outside wall insulated; and (c) inside wall insulated and outside wall temperature prescribed. The solution for temperature distribution was similar to that obtained b… more

Index of Refraction and Dispersion of Several Gases in Cerenkov Counter Use

Description: Measurements of index of refraction as a function of gas pressure for carbon dioxide, ethane, methane, sulfur hexafluoride, Freon 13, Freon 14, and Freon 23, which are suitable for Cerenkov Counter use, are reported. These gases do not react with Al or Ag mirror coatings, or other materials used in such counters, and have indices of refraction that are large enough to permit the use of these gases at reasonable pressures. Methane and ethane are both toxic and highly explosive; the remainder of … more

Irradiation of Metal-Fiber-Reinforced Thoria-Urania. Final Report- Metallurgy Program 6.2.4

Description: Randomly oriented fibers of either molybdenum or niobium were incorporated into hot-pressed pellets of 10, 30, and 50 wt% UO/sub 2/ in ThO/sub 2/ to improve thermal conductivity and thermal shock resistance. Pellets, 9.5 mm in diameter and 9.5 mm in length, were irradiated in NaK capsules, both bare and jacketed with Zircaloy-2, with the annulus between pellet and jacket filled with lead or helium. They were irradiated to burnups ranging up to 34 500 Mwd/T (1 0 x 10/sup 21/ fiss/cc) at central … more

Irreducible Representations of Line Groups: the Dynamics of Polymer Chains

Description: Abstract: "The symmetries of infinite polymer chain molecules are discussed using the concept of line groups. Explicit directions are given for obtaining the irreducible representations of line groups employing the formalism developed for three-dimensional space groups. Line groups containing primitive and nonprimitive operations are discussed. Detailed considerations of the line group Vh are given with specific applications to the polyethylene molecule. Directions for generating symmetry-adapt… more

The Neutron-Deficient Yttrium Isotopes Y$sup 82$, Y$sup 83$, and Y$sup 8$$Sup 4$

Description: Divergences in values of the half life of Y/sup 85/ have been resolved by discovery of a new sup 85/ isomeric state, and the half lives of Y/sup 84/ , Y/sup 83/, and Y/sup 82/ have been evaluated. Powdered arsenic metal targets were bombarded in the Berkeley heavy-ion linear accelerator with carbon ions. Determination by direct decay gives a half life of 39 plus or minus 1 min for Y/ sup 84/. Timed chemical separation values of 9 plus or minus 3 min and 8 plus or minus 2 min were obtained for Y… more

The Neutron-Deficient Yttrium Isotopes Y82, Y83, And Y84

Description: The neutron-deficient yttrium isotopes Y82, Y83, and Y84 have been produced by irradiations with the Berkeley heavy-ion linear accelerator. Where possible, identifications were made by establishing genetic relationships with known daughter or granddaughter activities. The half-life of Y84 determined by direct decay is 39+-1 min. By a series of timed chemical separations, the following half-lives have been established: Y82, 9+-3 min; Y83, 8+-2 min. No information pertaining to the radiations emi… more

ON THE REALITY OF THE EIGEN-VALUES FOR A ONE-GROUP N-REGION DIFFUSION PROBLEM

Description: A sufficient condition is presented for the reality of the eigen-values for a fairly general one-group, multiregion two-dimensional diffusion problem. The condition is also sufficient to insure the orthogonality of eigen-functions corresponding to distinct eigen-values. (D.L.C.)

OXIDATION OF TUNGSTEN AND TUNGSTEN BASED ALLOYS

Description: The results of studies related to the oxidation of tungsten and its alloys are presented. The pressure of WO/sub 3/ polymers over WO/sub 2/ was measured in a tungsten Knudsen cell andd found to agree with measurements in a platinum cell. Literature data for WO/sub 2/ and WO/sub 3/ were combined with vapor pressures determined to give thermodynamic values for W/sub 18/O/sub 49/and W/sub 20/O/sub 58/. Tungsten oxidation rates were measured from 800 to 1700 deg C and in pressures of oxygen between… more

Phase Transformations in Alumina. Technical Report, May to December 1961

Description: e transformation studies showed that synthetic aluminas produced in the laboratory were not transformed to alpha alumina at 400 to 700' deg n the presence of nitric acid and water vapor. Amorphous aluminn produced in the pilot plant was transformed to alpha alumina. This indicated that the amorphous alumina produced in the pilot plant is structurally predisposed to form alpha alumina. Most additives did not appear to have any special effects. Lithium formed zeta alumina, LiAl/sub 5/O/sub 8/. Ph… more
