极化电子与类氢重离子共振复合中的宇称不守恒效应
Parity nonconservation effect in resonance recombination of polarized electrons with heavy hydrogenlike ions
摘要：
研究了极化电子与重类氢离子在与相应的类氦离子双激发态共振情况下复合的宇称不守恒效应。假设在相对于入射电子动量的给定角度处检测到能量对应于双激发态到$2^1S_0$或$2^3P_0$态的单光子衰减的光子。对类氦钍（$Z = 90$）和钆（$Z = 64$）进行了计算，其中$2^1S_0$和$2^3P_0$能级接近交叉，因此PNC效应强烈增强。
英文摘要：
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 $2^1S_0$ or the $2^3P_0$ 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 $2^1S_0$ and $2^3P_0$ levels are near to cross and, therefore, the PNC effect is strongly enhanced.
