We have searched for optical rotation near the 8757-Å magnetic-dipole absorption line in atomic bismuth vapor. The experiment is sensitive to parity nonconservation in the weak neutral-current interaction between electrons and nucleons in atoms. We find R≡Im(E1M1)=(−0.7±3.2)×10−8, which is considerably smaller than the value R=−2.5×10−7 obtained by central-field calculations for this bismuth line using the Weinberg-Salam theory of neutral currents.

Measurement of Parity Nonconservation in Atomic Bismuth

Hollister, J.H. ; Apperson, G.R. ; Lewis, L.L. ; et al.

Parity-nonconserving optical rotation has been observed and measured on the 8757-ÅA magnetic-dipole absorption line in atomic bismuth vapor. The result, R≡Im(E1M1)=(−10.4±1.7)×10−8, is of the approximate size calculated with use of the Weinberg-Salam theory of the weak neutral-current interaction with sin2θW=0.23.
