Neutron Density Depression Due to an Oblate Spheroidal Detector

Neutron Density Depression Due to an Oblate Spheroidal Detector

Date: January 1954
Creator: Trammell, Margaret Ruth
Description: In this paper, two projects have been undertaken. First, Workman's calculations have been checked to a higher degree of approximation to determine the accuracy of his method. Second, a new set of boundary conditions has been developed for obtaining solutions of the neutron diffusion equation which do not depend on the solution of the equation inside the detector.

A Method for Calculating Foil Depression Factors

A Method for Calculating Foil Depression Factors

Date: June 1953
Creator: Workman, Billy J.
Description: As disc-shaped detectors are one of the primary means of measuring the neutron density, a better solution is desirable if the error due to the depression factor is to be made negligible. In this paper, an attempt is made to solve this problem in the oblate spheroidal co-ordinate system which most nearly describes the disc-shaped detector, so that solutions may be obtained that describe depression factors for detectors of varying thicknesses and radii.

Variational Wave Function for Sodium

Variational Wave Function for Sodium

Date: August 1953
Creator: Smith, Daniel Montague
Description: The practical method of applying the variation principle to the calculation of the energy of an atom demands a trial function which contains variable parameters. The previous work done using this approach was based on the use of some combination of hydrogenic wave functions containing parameters inserted in appropriate places. The present calculation of the energy of the eleven-electron atom has been brought about using this method.

Experimental Determination of the Scattering Cross-section of Ogives and Prolate Spheroids at Microwave Frequencies

Experimental Determination of the Scattering Cross-section of Ogives and Prolate Spheroids at Microwave Frequencies

Date: 1956
Creator: Rhoads, Wayne C.
Description: Because of the great difficulty of obtaining exact numerical values of cross-section, and because of the inherent uncertainties in interpreting and evaluating the approximate methods, accurate experimental cross-section data would be extremely useful to the radar engineer. It was with this purpose in mind that the present long-range research program in microwave scattering was undertaken. Of immediate interest were the scattering properties of the prolate spheroid, the ogive (formed by rotating the minor segment of a circle around the chord), and, for comparison, the long cylinder.

An Investigation for Gamma Rays Resulting from the Bombardment of As75 with 14 Mev Neutrons

An Investigation for Gamma Rays Resulting from the Bombardment of As75 with 14 Mev Neutrons

Date: 1957
Creator: Givens, Wyatt Wendell
Description: It is the purpose of this paper to set forth the method and results of studying the gamma rays resulting from the bombardment of As75 with approximately 14 Mev neutrons.

Quaternion Representation of Crystal Point Groups

Quaternion Representation of Crystal Point Groups

Date: August 1959
Creator: West, Richard Harrison
Description: The physical behavior of crystalline solids is very closely related to the internal symmetry of the crystal structure. For this reason it is desirable to represent mathematically this symmetry in such a way that the actual physical problems can be handled as they arise. In the case of this thesis the research has been guided by a list of desired properties for such a representation. No claim is made that the list is complete.
