摘要：

Parity nonconservation (PNC) effect in recombination of a polarized electron with a heavy H-like ion in the case of resonance with a doubly excited state of the corresponding He-like ion is studied. It is assumed that photons of the energy corresponding to the one-photon decay of the doubly excited state into the 2(1)S(0) or 2(3)P(0) state are detected at a given angle with respect to the incident electron momentum. Calculations are performed for helium-like thorium (Z = 90) and gadolinium (Z = 64), where the 2(1)S(0) and 2(3)P(0) levels are near to cross and, therefore, the PNC effect is strongly enhanced.
