Kinematics of the Relativistic Two-Body Problem

Description: Abstract: "The kinematics of elastic scattering, inelastic scattering, and the two body reaction problem is developed in the relativistic limit and exact expressions obtained for the energies, angles, and solid-angle transformations involved. The results are specialized for zero rest mass of one or more of the particles involved. An outline for the coding of the problem on the I.B.M. Electronic Data Processing Machine, Type 701 is presented."

Fall-Out Studies with a Laboratory Controlled Model

Description: From abstract: "To seek information for a better understanding of the phenomena involved in fall-out, a fireball effect was simulated in a small closed room by subjecting various materials to a high-current (~360 amp.) are produced between graphite electrodes, and anode being impregnated with radioactive materials. The time duration of the arc, power dissipated, and distance from the samples were controlled. The radioactivity which remained airborne, that which settled out onto the floor and it… more

Estimated Upper Bounds to the Half-Life of Thermal Decomposition of Ammonia, Hydrogen, Methane, and Propane

Description: An estimate was made of the upper bound for the half-time of dissociation at 100 atm for ammonia, methane, and propane at 2500 deg K and hydrogen at 5000 deg K. In each case a unimolecular reactron in the homogeneous gas phase was chosen as most suitable for this purpose. Slater's theory has been used to estimate the necessary frequency factors. The upper bounds to the half- time for dissociation range from 3 x 10⁻⁷ to 6 x 10⁻⁶ sec. Extrapolation of decomposition rate data obtained at --1000 de… more

Equations Representing Reactor System with Emphasis on KIB Digital Program

Description: "This report is written as a supplement to LAMS 2539. It is hoped that one will be able to read LAMS 2539, with emphasis on the fourth part (Memorandum N-4-79OU by 0. Farmer), with this memorandum to bridge the gaps and understand more about the model used and what the KIB Program can be used for. The system is defined by subsystems or subprograms: Thrust System, Heat Exchanger, Neutron Dynamics, Rod Actuator Dynamics, and Thermocouple Dynamics. The original Kiwi-B Flow System is included in th… more

Results of Elemental Analyses of Water and Waterborne Sediment Samples from the Proposed Cape Krusenstern National Monument, Alaska

Description: From abstract: During July-August 1976, water and sediments were collected for the Los Alamos Scientific Laboratory from streams and lakes over an area of -100 000 km2 around Kotzebue, Alaska. The sampling was by helicopter, as part of the NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) sponsored by the US ERDA. It was done according to rigorous, but simple, written procedures, at a nominal density of one location per 23 km 2, and included the 1400- to 1900-km2 area proposed for… more

Stability of a Linear Pinch With a Thick Boundary

Description: The stability of a linear pinch is investigated by means of the "6W" formalism of E. A. Frieman. It turns out that when attention is confined to the surface layers of the plasma, convenient stability criteria can be deduced for very general cylindrically symmetric distributions of magnetic field and plasma.

Gas Discharges : Lecture Series

Description: Most books on the subject of gas discharges describe the multiple banded structure which appears in the flow between two electrodes. This structure is actually due to the difficulty in getting electrons out of the cathode to support the discharge. These electrons are obtained by having a large enough potential drop near the cathode so that the positive ions may strike it hard enough to product secondary electrons. If one substitutes a hot cathode to produce a copious quantity of electrons, the … more

The Influence of a Precipitation Hardening Heat Treatment on the Hardness of Several Uranium-Molybdenum Alloys

Description: Four uranium alloys containing nominally 0.5, 1.0, 1.5, and 2.0 w/o molybdenum were investigated with respect to their response to hardening by heat treatment. The several alloys were heated at elevated temperatures to secure solid solution, then quenched and reheated at lower temperatures to obtain hardening. The procedure followed the well known industrial practice of solution treatment and precipitation hardening. The results showed that all the alloys could be hardened by a suitable heat tr… more

An Estimate of the Lapre Power and Steam Flow Characteristics

Description: A method of numerical solution is developed for calculating the Lapre coolant pressure drop and power output with variable coolant inlet pressure, flow rate, and reactor solution temperature. The results of a series of calculations are presented that show excessive pressure drops and sonic exit flow as the flow rate is increased and the inlet pressure is decreased. Both supercritical and subcritical coolant flow regions are investigated. Reactor power is shown to be strongly dependent on the so… more

Opacity of Air at High Altitudes and High Temperatures

Description: The opacity and thermodynamic properties of air at temperatures above 10 e.v. and densities below normal have been calculated under the guidance of H. Mayer in accordance with the prescription given in AECD 1870 (LA-647). Corresponding to given densities and temperatures, self-consistent distributions of electrons in bound states and their eigen energies are determined. With this information we compute the thermodynamic properties of air and the frequency-dependent absorption coefficients. Fina… more
