Electromagnetic Production Of Pion Pairs, Clayton D. Zerby

Doctoral Dissertations

The Pauli-Weisskopf theory of electromagnetic production of pion pairs has been a subject of interest in various connections for many years. Recently new interest has been stimulated in the theory because pion pair production is a possible means of investigating the - interaction. This approach, which was originally suggested by Pomeranchuk, is particularly valid in view of the increase in the cross section, when the strong pion-nucleus interaction is included, over that obtained by the original theory. The purpose of this work was to study the Pauli-Weiskopf theory with the objective of including the strong pion-nucleus interaction and developing an …

Concentric Tori In The Three-Spere, Charles Henry Edwards Jr.

Doctoral Dissertations

A torus is the topological product of two circles, while a solid torus is the topological product of a circle and a disk. Two solid tori B1 and B2 in the three-sphere S^3, with B2 interior to B1, are said to be concentric if and only if the closure of B1-B2 (the set of points in B1 but not in B2) is homeomorphic to the topological product of a torus and a closed interval. Two tori in S^3 are concentric if and only if they are respectively the boundaries of two concentric solid tori.

The Geology Of The Sequatchie Valley Overthrust Block, Sequatchie Valley, Tennessee, Robert Calvin Milici

Doctoral Dissertations

Introduction: Abbreviated

The purpose of this investigation was twofold: (1) to decipher the nature of the thrust faulting of the anticline; and, (2) to study the stratigraphy of the Paleozoic formations of the Sequatchie Valley.

Pseudoscalar Interaction In Nuclear Beta Decay, Chander Perkash Bhalla

Masters Theses

In Chapter I, the statement of the problem considered in this dissertation is given: the investigation of the existence of the pseudo­ scalar interaction by the formulation of the theoretical expressions for the beta longitudinal polarization and the beta spectrum in 0 --> 0 (yes) beta transitions and by a comparison of the existing experimental data with the developed theory.

In Chapter II, we explain the reasons for the incorrectness of the conventional treatment of the pseudoscalar interaction, and then give the correct form of the operator for this interaction.

In Chapter III, using the correct form of the pseudoscalar …

Part A: Studies Of Organic Solvent Enhancements In Flame Photometry; Part B: Studies Of The Extraction And Flame Emission Of Magnesium, Jack Hudgens Knox

Doctoral Dissertations

Summary

The present investigation has been concerned with the study of several parameters which influence the flame photometric emission of elements in an effort to elucidate the nature of the intensifications observed with organic solvents. Parameters such as flames temperature, OH band intensity, ionization, sample flow rate, and the emission intensities of different elements in different solvents have been studied.

Metal-Metal Ion Exchange Of Mercury And Some Amalgams, Richard Charles Legendre

Doctoral Dissertations

Proposed Problem

The objective of this research was to investigate the behavior of metal ions in aqueous solution in their exchange with atoms of the same metal, but where the metallic phase would be in the liquid state.

Research along these lines but involving solid metallic phases has demonstrated that the exchangeability of an ion with a solid metal probably depends on the ability of the metal to re-form its surfaces when in contact with these solutions. A preceding section has reported on the sensitivity of exchange to any of the various processes that can affect the nature of the …

Gas Chromatography Of Hydrogen-Deuterium Mixtures, Paul Payson Hunt

Doctoral Dissertations

Introduction: In recent years the gas chromatographic method has found widespread applications, chiefly for analytical purposes. This method is principally employed for the separation, identification, and quantitative determination of volatile compounds. It is potentially of great value for the quantitative determination of mixtures of the hydrogen isotopes. The development of a rapid, convenient, and inexpensive method for the analysis of the hydrogen isotopes would be a valuable addition to many laboratories, especially those where a mass spectrograph is unavailable. This problem was undertaken in an attempt to develop further the chromatographic method for the separation and quantitative determination of hydrogen …
