Abstract

Electroweak radiative corrections to the matrix elements 〈ns_1/2|H_PNC|n^\ensuremath'p_1/2〉 are calculated for highly charged hydrogenlike ions. These matrix elements constitute the basis for the description of the most parity-nonconserving processes in atomic physics. The operator H_PNC represents the parity-nonconserving relativistic effective atomic Hamiltonian at the tree level. The deviation of these calculations from the calculations valid for the momentum transfer q²=0 demonstrates the effect of the strong field, characterized by the momentum transfer q²=m_e² (m_e is the electron mass). This allows for a test of the standard model in the presence of strong fields in experiments with highly charged ions.
