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

\beta

are found to be -0.4% and -1% respectively. The weak charge of

^{133}

Cs is

Q_W=-72.5 \pm 0.7

in agreement with the standard model.
