We derive the electroweak radiative corrections to the basic PNC atomic tra
nsition amplitude for highly charged hydrogenlike ions. In the case of high
ly charged ions (HCl) effects of strong fields are reflected by the momentu
m transfer q(2) involved. It is of the order q(2) approximate to m(e)(2) in
HCl. while q(2) approximate to 0 in neutral atoms. This may open the possi
bility to search for "new physics" beyond the Standard Model and to test th
e Standard Model in experiments with HCl.
