Query: Prospects for Parity Non-conservation Experiments with Highly Charged
  Heavy Ions   We discuss the prospects for parity non-conservation experiments with highly
charged heavy ions. Energy levels and parity mixing for heavy ions with two to
five electrons are calculated. We investigate two-photon-transitions and the
possibility to observe interference effects between weak-matrix elements and
Stark matrix elements for periodic electric field configurations.
