    "abstract": "We report a new calculation of the parity non-conserving E1 amplitude for the\n6p_{1/2} -\u003e 6p_{3/2} transition in Tl. Our result for the reduced matrix\nelement is $E1_{PNC}=-(66.7 \\pm 1.7) i 10^{-11} (-Q_W/N)$ a.u. Comparison with\nthe experiment of Vetter et al [PRL,{\\bf 74},2658 (1995)] gives the following\nresult for the weak charge of $^{205}$Tl: $Q_W/Q_W^{SM} = 0.97 (\\pm\n0.01)_{expt} (\\pm 0.03)_{theor}$, where $Q_W^{SM}=-116.7$ is the standard model\nprediction. This result confirms an earlier conclusion based on the analysis of\na Cs experiment that atomic PNC experiments are in agreement with the standard\nmodel.",
