Abstract

We report a calculation of the parity nonconserving (PNC) E1 amplitude for the 6p_1/2\ensuremath→6p_3/2 transition in ²⁰⁵Tl. Our result for the reduced matrix element is (E1)_PNC=\ensuremath-(66.7\ifmmode±\else\textpm\fi1.7)\ifmmode×\else\texttimes\fii10^\ensuremath-11(\ensuremath-Q_W/N) a.u. Comparison with the experiment of Vetter et al. [Phys. Rev. Lett. 74, 2658 (1995)] gives the following result for the weak charge of ²⁰⁵Tl: Q_W/Q_W^SM=0.97(\ifmmode±\else\textpm\fi0.01)_expt(\ifmmode±\else\textpm\fi0.03)_theor, where Q_W^SM=\ensuremath-116.7\ifmmode±\else\textpm\fi0.1 is the standard-model prediction. This result confirms an earlier conclusion based on the analysis of a Cs experiment that atomic PNC experiments are in agreement with the standard model.
