Abstract Parity-nonconserving (PNC) atomic effects originate from the electroweak interaction of atomic electrons with the nucleus via Z-boson exchange. Comparing experimental results with theoretical predictions of the standard model allows to search for ”new physics ” beyond the standard model (e.g., a second Z-boson or new fermions) [1]. In the case of neutral atoms here is the discrepancy between theoretical and experimental results for PNC effects in the case of neutral atoms that might be explained by the uncertainties in the calculations caused by the interelectronic interactions, correlation effects etc. In highly-charged ions (HCI), on the other hand, the binding to the nucleus dominates by far the electronelectron interaction. The spin-independent part of an effective weak interaction Hamiltonian mediated by a Z-
