    "abstract": "We discuss a parity nonconserving asymmetry in the cross section of KLL\ndielectronic recombination of polarized electrons on the hydrogen-like ions\nwith $Z \\lesssim 60$. This effect is strongly enhanced because of the\nnear-degeneracy of doubly-excited $2l2l\u0027$ states of opposite parity in He-like\nions. For ions with $Z \\sim 30$ the asymmetry is of the order of $10^{-9}$. For\n$Z \\approx 48$ a level crossing takes place, leading to the PNC asymmetry of\n$\\pm 5\\times 10^{-9}$, which is $10^8$ times greater than the basic strength of\nthe weak interaction in atoms.",
