Photon-photon polarization correlations as a tool for studying parity non-conservation in heliumlike Uranium

arXiv:1103.4592 · doi:10.1103/PhysRevA.83.052505

Abstract

Due to electron-nucleus weak interaction, atomic bound states with different parities turn out to be mixed. We discuss a prospect for measuring the mixing parameter between the nearly degenerate metastable states 1s_{1/2} 2s_{1/2} : J = 0 and 1s_{1/2} 2p_{1/2} : J = 0 in heliumlike Uranium. Our analysis is based on the polarization properties of the photons emitted in the two-photon decays of such states.
