12	The Ratio of Vector and Axial Vector Coupling Constants in the Beta-Decay of Rb87 / Ratio of Coupling Constants in the Beta-Decay of Rb87 Keech, George 09 1900 (has links) The purpose of this work is to evaluate the ratio of the vector and axial vector coupling constants in the beta-decay of Rb^87. Particular attention is given to determining the sign of the ratio. All this is accomplished mainly by a conic analysis of the beta-spectrum and the calculation of a matrix element ratio. The results obtained indicate that the ratio of the coupling constants is negative. Due to uncertainties in nuclear matrix elements, only an approximate absolute value for the ratio can be secured. These results are consistent with other present evidence. / Thesis / Master of Science (MSc) vector axial vector vectors axial vectors vector coupling constants axial vector coupling constants beta-decay beta-decay of Rb87 Rb87 rubidium-87 physics coupling constants
