Phys. Rev. Lett. 85, 1618–1621 (2000)Reconciliation of the Measurement of Parity Nonconservation in Cs with the Standard ModelReceived 29 November 1999; revised 8 May 2000; published in the issue dated 21 August 2000 Contributions from the Breit interaction in atomic structure calculations account for 1.3σ of the previously reported 2.5σ deviation from the standard model in the 133Cs weak charge [S. C. Bennett and C. E. Wieman, Phys. Rev. Lett. 82, 2484 (1999)]. The updated corrections for the neutron distribution reduce the discrepancy further to 1.0σ. The updated value of the weak charge is QW(133Cs) = -72.65(28)expt(34)theor. © 2000 The American Physical Society URL:
