Abstract

We calculated the parity nonconserving (PNC) 6s -> 7s amplitude in Cs. In the Dirac-Coulomb approximation our result is in a good agreement with other calculations. Breit corrections to the PNC amplitude and to the Stark-induced amplitude β\beta are found to be -0.4% and -1% respectively. The weak charge of 133^{133}Cs is QW=72.5±0.7Q_W=-72.5 \pm 0.7 in agreement with the standard model.
