Atomic parity-violation phenomena arising due to the weak interaction of atomic electrons with nuclei have been in the focus of experimental and theoretical research for several decades [1,2].
In this study, the focus lies on the influence of the mixing of opposite-parity ionic levels on the excitation rates in highly charged ions. This mixture arises due to an external electric field and the weak interaction between electrons and the nucleus. In order to reinvestigate this "Stark-plus-weak-interaction" mixing, detailed calculations are performed in hydrogen- and lithium-like ions. In particular, we focus on the difference between
the excitation rates obtained for right- and left-circularly polarized incident light. This difference arises due to the parity violating mixing of ionic levels.
