Factors Affecting the Precipitation of Tubanyl Peroxide from Gunk Solutions at Reduced Temperatures

Description: This paper reports work carried out to determine the factors necessary to give a filterable precipitation and determine the effects of these factors on the quantitativeness of the precipitation, and how any tendency to increase the tuballoy solubility may be overcome.

A Solubility Method of the Determination of Non-Volatile Material in Tetrachloride Charges

Description: Abstract: "This report suggests using methyl acetate extraction of charge material as a means of determining the non-volatile residue. It is shown that the volatile constituents of charge material are all extremely soluble in methyl acetate whereas the non-volatile materials are quite insoluble. Percent NVH on several samples of charge material by this method are reported and discussed."

Development of Equipment for the Purification of Mercury by Distillation

Description: Abstract: "An investigation of the mercury salvage program has resulted in the development of an improved high compacity type of distillation apparatus. The still, electrically heated and essentially automatic in its operation, will produce at a rate greater than 75 pounds per hour and develop a product 99.99% pure or better. This still will handle the lowest grade crude of amalgam that can pass through the feed lines and will continue to develop a pure prodcut for comparatively long periods of… more

The Solubility of Helium in Tuballoy

Description: This technical report summarizes the work done in attempting to determine the solubility of helium in tuballoy. In general, the method used has been to allow the tuballoy to stand in contact with helium at one atmosphere presume at a fixed temperature for an extended period, then to pump off the excess helium to a low pressure in as short a time as possible (10-6 mm of Hg or less). The system was then closed off and the pressure increase was measured by a suitable gauge as a function of time.… more

Report on SOM Investigations in Arizona (Except the Plateau Province Area)

Description: From summary: Union Mines' examination of Arizona's pegmatites, lode deposits of the central and southeastern parts of the state, and heavy mineral concentrates from few placer deposits indicates that SOM is practically non-existent in the first two and that minor amounts of monazite and possibly other S-37 minerals are present in the last.

Measurement of Weak Neutron Intensities by Szilard-Chalmers Reaction in Calcium Permanganate Solution

Description: From abstract: "A sensitive method for measuring the intensity of weak neutron sources by measuring induced Mn56 beta activity after concentration by a Szilard-Chalmers process has been developed. The practical detection efficiency for Ra-Be neutron is 7.8%; the procedure is capable of detecting a neutron intensity of about one neutron per second."

Studies in Beta and Gamma Ray Spectroscopy

Description: The study of artificial radioactive isotopes is at the present time one of the most important topics in nuclear research. It involves the establishment of a detailed term scheme for the disintegration in question. Not only are the energies of the components of the different beta and gamma radiations of interest, but also their intensities. These data give information concerning the probabilities of transitions between the different nuclear energy levels. From them it is possible to draw con… more

Present Status of the Bevatron R. F. System

Description: The general method of controlling the radio frequency for the full scale Bevatron will be the same as that used on the 1/4 scale machine. The details of course will be modified to meet the requirements of greater range, higher output voltage and closer tracking tolerances. In addition, there is the added complication introduced by the current ripple.

High Energy Excitation Functions in the Heavy Region

Description: The electrostatically deflected beam of the 184-inch cyclotron has been used with the stacked foil and absorber technique to determine the excitation functions. The data are presented graphically and discussed individually for each of the reactions. The results are discussed in terms of compound nucleus formation, transparency effects, and other factors in order to arrive at a qualitative picture for the mechanism of high energy nuclear reactions with heavy nuclei.
