The Counting Efficiency of Counter Tubes with Aluminum, Copper and Gold Cathodes for X-Rays in the Range 5 Kev to 60 Kev

Description: The author's measurement using counting tubes were performed with an X-ray beam, produced by an X-ray tube. The X-ray beam impinges on only a very small part of the counting tube. In this work the counting efficiency of counting tubes with A1-Cu- and Au-cathodes is determined for X-radiation in the range 5 Kev to 60 Kev.

The Creep of Zirconium in Water

Description: Introduction:"Very little is known about the mechanical properties of zirconium and, in view of this the Atomic Energy Commission requested Sylvania to evaluate the creep characteristics of this metal at various temperatures. Tests at room temperature (25 C) and at 200 C have been completed, the tests having been conducted in air. The data obtained from these tests form the basis of this report. Future tests will be conducted in an atmosphere of water at the desired testing temperature."

The Extrusion of Beryllium

Description: Abstract: "A method for the extrusion of beryllium into rods and tubing has been developed. The operation is carried out between 1500 and 1900 F and the billet is clad in a layer of soft iron to prevent contact between it and the die steals. Extruded beryllium has much more strength and ductility than cast metal due to the crystal refinement which occurs as a result of the fabrication operation."

Heats of Formation of Some Aqueous Ions of Americium

Description: Abstract: "The heats of formation of Pr-(+3) (aq.) and La-(+3) (aq.) have been measured in 1.5M HCl at 25 C. to be -165.9 +/- 0.9 kcal/mol and -167.0 +/- 0.7 kcal/mol, respectively. The heat of formation of Am-(+3) (aq.) under the same conditions was found to be -161.3 +/- 1.4 kcal/mol. The latter value made it possible to calculate the heat of formation of Am-(+4) (aq.) as -112.2 kcal/mol. It was impossible at this time to determine the heats of formation of AmO2+ (aq.) and AmO2++ (aq.)."

Removal of Submicron Aerosol Particles From a Moving Gas Stream by the Condensation Center Effect

Description: From Introduction: "Many investigations of suitable processes for eliminating the particulate matter from the effluent gas streams of manufacturing processes have been carried out. During and immediately following the last war, the advent of large installations dealing with radioactive chemicals and their processes, has added new impetus and direction to those investigations. One such investigation will be herein described."

The Scattering of 31.8 Mev Protons by Protons Using Proportional Counter Detectors

Description: The basic experiment consists of causing a beam of protons to impinge upon an accumulation of relatively stationary protons (hydrogen gas) and to measure the number of protons scattered as a function of the scattering angle. A description of the arrangement and alignment of equipment with the 32-Mev beam of the Berkeley linear accelerator is included. The data have been analyzed statistically and results have been indicated.

Production of Pi-Mesons in Lead by High Energy Proton Bombardment

Description: Our knowledge of the properties of mesons and their interactions with nuclei has come from two sources. Studies of cosmic ray phenomena provided the earliest information. The discovery that mesons may be produced artificially by bombardment of nuclei with radiations from high energy accelerators has, on the other hand, made it feasible to undertake a wide variety of investigations under more controlled conditions than is possible in cosmic ray experiments. In such experiments mesons have bee… more
