Design and Properties of a Neon Filled Spark Chamber in a Magnetic Field

Description: Introduction: Recently a new type of charged particle detector, the so-called spark chamber, has been developed. The detector has certain advantages in high energy physics over bubble chambers aside from its much lower cost.

Sanitary Engineering Aspects of Long-Range Fallout from Nuclear Detonations

Description: From abstract: Results of a study of the sanitary engineering aspects of fallout from nuclear weapons are reported. Data were obtained from: a. Weekly surface water samples from 22 stations on streams and reservoirs in Eastern Massachusetts, collected from March, 1952 to July, 1953, and assayed for radioactivity. b. Weekly rain samples from March to July, 1953. c. Stream mud and soil samples collected before and after a large fallout. d. Results of fallout activity measurements by others based on samples from Massachusetts and the vicinity of Rochester, New York. Plots are presented showing the relations of the radiological data to the timing of detonations and the daily precipitation and showing daily deposition of activity and concentration in runoff. Runoff coefficients for fallout radioactivity are calculated.

On the Three-Dimensional Instability of Laminar Boundary Layers on Concave Walls

Description: Memorandum presenting a study of the stability of laminar boundary layer profiles on slightly curved walls relative to small disturbances, in the shape of vortices, whose axes are parallel to the principal direction of flow. The result in an eigenvalue problem by which, for a given undisturbed flow at a prescribed wall, the amplification or decay is computed for each Reynolds number and each vortex thickness.

Fission and Spallation Competition in Ra²²⁶, Th²³⁰, U²³⁵, and Np²³⁷

Description: This report follows the radiochemical study of fission and spallation products produced by bombardment of U-235 with 18- to 16-Mev helium ions and of the spallation products produced by 8- to 23-Mev deuteron bombardments of Np-237.

Capacity Factors in the Performance of Perforated Plate Distillation Columns

Description: From abstract: "A study of factors affecting the vapor handling capacity of perforated plate liquid-vapor contacting columns. Vapor phase pressure drop across plates, liquid entrainment upward from plate to plate, and plate stability were investigated as functions of operational and geometric column parameters."

The Method of Moments in Quantum Mechanics ; The [Pi]-Mesic Disintegration of the Deuteron

Description: The following report contains two reports to summarize a thesis: first, a report describing the classical moment techniques of Tchebycheff, Markov, and Stieltjes that have been applied to the problem of diagonalizing the Hamiltonian operator; and the second report describes an investigation of the higher-order corrections to the mesic disintegration of deuterons that is considered.

Compton Scattering on Nucleons

Description: From introduction: "The present paper deals with a classical calculation in which some of the meson effects can be included to all orders in the meson-nucleon coupling coupling constant, in particular those having to do with the gyration of the nucleon spin and isotopic spin. Such a treatment leads to results qualitatively different from the weak coupling calculations."
