我们研究了初始处于基态的极化电子在重类氦离子上的弹性散射中的宇称非守恒效应。通过调整入射电子与相应类锂离子的准准双激发态共振的能量来增强宇称违逆。我们考虑两种可能的情况。在第一种情况下，我们假设测量了散射电子的极化，而在第二种情况下，它没有被检测到。对于第二种情况，我们提出了一种改进的电子束离子源（EBIS）实验方案，其中电子散射中宇称破坏的检测似乎是可能的。
We investigate the parity nonconservation effect in the elastic scattering of polarized electrons on heavy He-like ions, being initially in the ground state. The enhancement of the parity violation is achieved by tuning the energy of the incident electron in resonance with quasidegenerate doubly-excited states of the corresponding Li-like ion. We consider two possible scenarios. In the first one we assume that the polarization of the scattered electron is measured, while in the second one it is not detected. For the second scenario we propose a scheme of a modified electron beam ion source (EBIS) experiment where the detection of a parity violation in the electron scattering seems possible.
