Journal Article · · Phys. Rev. Lett.; (United States)
We report measurements of the Stark amplitude coefficients ..cap alpha..,..beta.. for the transition 6P/sub 1/2/..-->..7P/sub 1/2/ (293 nm) in /sup 205/Tl in an external electric field E. ..cap alpha.. is determined by measurement of absorption of 293-nm light at the F = 1..-->..F = 1 resonance in a cell with known electric field and interaction length, and calibrated density. ..beta.. is determined from the ratio ..beta../sup 2//..cap alpha../sup 2/ of intensities of F = 0..-->..F = 1 and F = 0..-->..F = 0 lines in fluorescence. We obtain ..cap alpha.. = (1.31 +- 0.06) x 10/sup -5/..mu../sub 0/ cm/V, ..beta.. = (1.09 +- 0.05) x 10/sup -5/..mu../sub 0/ cm/V (where ..mu../sub 0/ is the electron Bohr magneton). These results indicate substantial shielding by core electrons. ..beta.. is combined with previous measurements of Im(scrE/sup P//..beta..), where scrE/sub P/ is the parity-nonconserving electric dipole amplitude, to yield scrE/sub P/. .AE
