The Angular Distribution and Total Flux of Neutrons Obtained from the Deuterium-Tritium Reaction
Date: 1956
Creator: Duggan, Jerome L.
Description: Mono-energetic neutrons have been produced with the low-voltage Cockroft-Walton accelerator at North Texas State College using two different reactions. It is the purpose of this paper to report the angular distribution and total flux of the neutrons obtained from the T(D,n) reaction.

Gamma Rays from Cs¹³³ by Inelastic Scattering of Neutrons
Date: August 1960
Creator: McDonald, Perry Frank
Description: The purpose of this investigation was to observe the excited states of the Cs¹³³ nucleus when neutrons are inelastically scattered from the nucleus.

A System for Measurement of Negative-Ion Charge-Exchange Cross Sections
Date: January 1960
Creator: Wingo, Dale T.
Description: A radio-frequency positive-ion source and a fifty-kilovolt linear accelerator were designed and constructed in order to produce sizable quantities of hydrogen, helium, nitrogen, neon, and argon. Plans were then made to equip this ion source with charge-exchange apparatus suitable for charge-exchange cross-sectional measurements. It is the purpose of this paper to present the design of the equipment and to present operational knowledge of the equipment and of ion beams which are producible.

Gamma Ray Response of a CsI(T1) Crystal to 14 Mev Neutrons
Date: August 1958
Creator: Young, Jack Carter
Description: The purpose of this paper is to study the possible excited states in the nucleus of Cs133. At North Texas State College a 100-Kev Cockcroft-Walton accelerator has been constructed for use as a neutron source for exciting various nuclei and for studying the gamma spectra obtained to determine their energy levels.

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.

Design and Construction of a Positive Radio-Frequency Ion Source for the Production of Negative Ions
Date: August 1958
Creator: Thompson, B. Cecil
Description: It is the purpose of this paper to present a detailed account of the design and construction of this positive-ion source and associated equipment.

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.

Dipole Moments of Olefinic Esters
Date: 1952
Creator: Poteet, Horace M.
Description: It is the purpose of this thesis to investigate the applicability of the Debye equation to measurements dipole moments of polar compounds in dilute solutions of non-polar solvents more fully than has been done by previous workers at this institution.

Potential Distribution of an Electrical Source-Sink Combination Along the Axis of an Infinite Cylinder
Date: 1953
Creator: Parish, Edward R.
Description: In the present paper, an attempt is made to obtain the potential distribution in the case of two such charges, a source-sink combination, located on the axis of a bore hole drilled through an infinite, homogeneous medium.
