Parity nonconservation effect in resonance recombination of polarized electrons with heavy hydrogenlike ions

Abstract

Parity nonconservation (PNC) effect in recombination of a polarized electron with a heavy H-like ion in 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 the $2^3{P}_0$ state are detected at a given angle with respect to the incident electron momentum. Calculations are performed for heliumlike 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.
