Abstract

Within the framework of standard electroweak gauge theory, parity-violation effects on the Auger emission from atomic ions are examined. Highly charged ions are prime candidates due to their simple atomic structure and large electroweak charge. To be specific, the Auger decay of the 2[ital s][sup 2] [ital J]=0 level in U[sup 90+] is analyzed. In QED, the polarization-asymmetry parameter is identically zero. It is found that neutral-current mixing of the 2[ital s][sup 2] [ital J]=0 and 2[ital s]2[ital p] [ital J]=0 levels yields a polarization asymmetry of 10[sup [minus]7].
