Abstract: We discuss a parity nonconserving PNC asymmetry in the cross section ofdielectronic recombination of polarized electrons on multiply charged ions withZ>40. This effect is strongly enhanced for close doubly-excited states ofopposite parity in the intermediate compound ion. Such states are known forHe-like ions. However, these levels have large energy and large radiativewidths which hampers observation of the PNC asymmetry. We argue thataccidentally degenerate states of the more complex ions may be more suitablefor the corresponding experiment.
