PARITY NONCONSERVING OPTICAL ROTATION IN ATOMIC LEAD

Emmons, T.P. ; Reeves, J.M. ; Fortson, E.N. ;

The search for parity nonconservation in heavy elements has been extended to the 1.28-μm P03→P13 magnetic dipole transition in atomic lead. The experimental result, R=Im(E1M1)=(−9.9±2.5)×10−8, agrees, within the present uncertainties in experiment and atomic theory, with the prediction, R=−13×10−8, derived from the Weinberg-Salam-Glashow theory of weak neutral-current interactions.

Experimental verification of the Kramers-Kronig relation at high energy

Alvensleben, H. ; Becker, U. ; Biggs, P.J. ; et al.

The real part of the forward amplitude for Compton scattering on protons was measured through the interference between the Compton and Bethe-Heithler amplitudes by detecting the zero-degree electron pairs asymmetrically. The measurement was made at an average photon energy of 〈k〉=2.2 GeV, and an average momentum transfer to the recoil proton 〈t〉=−0.027 (GeV/c)2. The result confirms the prediction of the Kramers-Kronig relation.

Measurement of Parity Nonconservation in Atomic Bismuth

Hollister, J.H. ; Apperson, G.R. ; Lewis, L.L. ; et al.
Phys.Rev.Lett. 46 (1981) 643-646, 1981.
Inspire Record 942914 DOI 10.17182/hepdata.20642

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.
