Abstract

The amplitude of the parity-nonconserving transition between the 6s and 7s states of cesium was precisely measured with the use of a spin-polarized atomic beam. This measurement gives lm(El_Pnc)/β = -1.5935(56) millivolts per centimeter and provides an improved test of the standard model at low energy, including a value for the S parameter of -1.3(3)_exp(11)_theory. The nuclear spin-dependent contribution was 0.077(11) millivolts per centimeter; this contribution is a manifestation of parity violation in atomic nuclei and is a measurement of the long-sought anapole moment.
