Abstract: An airborne radiometric survey of parts of the east flank of the Big Horn Mountains was begun on June 23, and completed on August 27, 1952. An area of approximately 250 square miles was covered, and only two anomalies were found in the entire area. Flight lines were arranged in accordance with the geology of the area, particular attention being given to formations the stratigraphic equivalents of which are known to be uranium bearing in other areas. Two additional zones of radioactivity were found by ground investigation, but assays from both the ground and the airborne discoveries showed no economic uranium deposits.

Abstract: The Happy Jack uranium deposit of White Carron, San Juan County, Utah, was studied in connection with an Atomic Energy Commission exploration program. The major uranium ore control is a paleostream channel containing sediments of the Shinarump conglomerate. Intrachannel controls include organic matter, lithologic variations, and channel "lows". Microscopic studies reveal that uraninite, the primary ore mineral, occurs as cement and as a replacement of organic material. Both the uraninite and copper sulfides replace secondary quartz overgrowths. Crystals of chalcopyrite, chalcocite, and pyrite occur one within the other. Resolution of bornite and chalcopyrite is present. Uraninite is dated as later than the secondary overgrowths and of about the same age as the copper sulfides.

"Work has continued on high temperature methods for processing irradiated uranium fuel. Additional results have been obtained with fused halide treatment, solid scavengers and direct Pu distillation. With fussed fluorides about 95 per cent of the Pu was removed from a uranium sample, while treatment of uranium with HC1 gas removed almost all the Pu and many fission products. treatment of molten uranium with uranium oxide removed a substantial fraction of the fission products without removing Pu. Uranium carbide treatment results were similar to the oxide but not as effective. A small scale distillation of Pu from uranium showed that Raoult's law is obeyed."

The Grüneisen constant, as evaluated from the equation of state, is obtained for an Einstein solid. the presence of a state of finite hydrostatic pressure is taken into account explicitly by means of Murnaghan's theory of finite strain, to obtain the Grüneisen parameter's on the Debye and Einstein models. Results are identical in the two cases with the corresponding values obtained without use of the formal theory of finite strain.

The following report follows the study on economics of nuclear power generation using a light water reactor.

From abstract: High velocity disturbances are observed to propagate along the walls of a high explosive operated shock tube in advance of the plane shock. Experiments are presented which determine the dependence of the geometry, energy, and velocity of the disturbance on such variables as the gas contained in the shock tube, the shock strength, and the roughness and composition of the supporting boundary. A model is constructed to explain the flow within the disturbance. Arguments are presented which show the disturbance to result from radiation originating in the luminous plane shock...The purpose of this paper is to present the results of initial investigations made in an effort to describe the phenomenon of strong shocks developed in a shock tube by the detonation of high explosive charge.

Abstract: Some proportional fission neutron counters are described with information on methods of preparation and details of a circuit for a portable model. The portable instrument has an efficiency of .01% for neutrons from polonium beryllium sources.

Abstract: The rate of reaction of oxygen with arc-melted and rolled iodide thorium has been found to obey the parabolic rate law in the temperature range of 850 to 1415 C at 1 atmosphere pressure. The rate constant can be expressed as k = 6 x 10⁷ x e⁻⁶³³⁰⁰/RT cm²/sec. The energy of activation, 63,300 cal/mole, has a probable error of 2,100 cal/mole.

Report discussing an experiment in which samples of initially ordered and disordered copper-gold alloy were exposed to the neutron flux of a graphite moderated nuclear reactor. "Two specimens were irradiated at the same time and at the same position in the reactor. Their temperature was controlled at 80°C. Electrical resistivity measurements were made on the specimens during the course of the irradiation."

At present there are three Laboratories actively engaged in analyzing samples for the "SUNSHINE PROGRAM"; Lamont Geological Observatory, University of Chicago and the New York Health and Safety Laboratory. The U.S. Department of Agriculture Laboratories at Beltsville ae preparing samples for the University of Chicago, and are running normal strontium analyses. In order that the results reported from each of the three laboratories may be used to evaluate Sr90 distribution, a cooperative program has been in operation since August of 1953. This preliminary report lists the results on samples received and distributed by HASL. It is hoped that complete results from all laboratories will be available soon.

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 conclusions regarding the mechanism of the disintegration and to correlate the spina and parities of the levels.

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.

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.
