This thesis describes the measurement of Stark amplitude coefficients and US for the 6SP/sub 1/2/ 7SP/sub 1/2/ transition of SVTl in an external static electric field E. The coefficient is determined by measuring the absorption of linearly polarized 293 nm light at the F=1 F'=1 resonance in a cell with known electric field and interaction length, and calibrated thallium density. Then US is determined from the ratio US S/ S of intensities of the F=0 F=1 and F=0 F=0 resonance lines in fluorescence. The final results are = (1.30 +- 0.06) x 10 V 0 cm/V and US = (1.08 +- 0.05) x 10 V 0 cm/V (where 0 = electron Bohr magneton). US is combined with a previous measurement of Im EPSILON/sub p//US to yield the parity non-conserving electric dipole amplitude EPSILON/sub p/. 25 refs., 25 figs., 1 tab.
