Description
We discuss a parity nonconserving asymmetry in the cross section of KLL dielectronic recombination of polarized electrons on the hydrogenlike ions with Z < or approx. 60. This effect is strongly enhanced because of the near degeneracy of doubly excited 2l2l' states of opposite parity in He-like ions. For ions with Z∼30 the asymmetry is of the order of 10-9. For Z≅48 a level crossing takes place, leading to the PNC asymmetry of -1.3x10-8, which is 108 times greater than the basic strength of the weak interaction in atoms
