摘要：

Including the Breit interaction leads to a 0.6% reduction in the magnitude of the 6s-7s parity-nonconservation (PNC) amplitude in Cs-133, confirming a result recently obtained by A. Derevianko [Phys. Rev. Lett. 85, 1618 (2000)]. A revised value of the theoretical PNC amplitude for Cs-133 is given; the corresponding value of the weak charge shows no noticeable deviation from the standard model.
