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.

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 document analyzes studies to test the use of asphalt as a fast neutron moderating substance to be incorporated as a part of a pile shield.

Discussing velocity logging carried out during six weeks of fieldwork in 1955 through contracts with the Texas Company.

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.

From abstract: "This report describes methods used for radiochemical analysis of fission products most used in the Experimental Biology Section. The report includes methods of analysis of Sr89, Ba140-La140, Zr95-Cb95, Ce144-Pr144, and Y91 by standard chemical procedures. In addition, a method of analysis by use of an absorption curve is described in some detail for Zr95-Cb95 mixtures. The absorption curve method makes possible rapid determination of percentage composition of a mixture of isotopes with a minimum of chemical manipulation by utilizing the differences in absorption characteristics of the emitted rays."

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."

From objectives: "To establish, by literature search, analysis and design, the engineering and fabrication requirements for modifying reactor components and developing and installing the necessary instrumentation to carry out a fuel temperature and flow measurement experimental program."
