Abstract

We calculated the parity-nonconserving (PNC) 6s\ensuremath→7s amplitude in Cs. In the Dirac-Coulomb approximation our result is in good agreement with other calculations. Breit corrections to the PNC amplitude and to the Stark-induced amplitude \ensuremathβ are found to be \ensuremath-0.4% and \ensuremath-1%, respectively. The weak charge of ¹³³Cs is Q_W\phantom\rule0ex0ex=\phantom\rule0ex0ex\ensuremath-72.5\ifmmode±\else\textpm\fi0.7 in agreement with the standard model.
