我们通过实验表明，双电子复合中发射的跃迁是强极化的，尽管它本质上是非极化跃迁。这种意外的极化被证明是由于辐射复合的量子干涉造成的。已经在不对称共振轮廓上研究了干涉效应，但从未在偏振上研究过。在这封信中，我们表明，对偏振的影响可能是由与造成不对称的交叉项不同的交叉项引起的，即使对于表明小干扰的近对称共振，也会导致意外的大偏振。
We experimentally show that thetransition inemitted in dielectronic recombination ofis strongly polarized, although it is an intrinsically unpolarizedtotransition. This unanticipated polarization is shown to be due to quantum interference with radiative recombination. The interference effect has been studied on an asymmetric resonance profile but has never been studied on polarization. In this Letter, we show that the effect on polarization can arise from a different cross term than that responsible for asymmetry, resulting in unexpectedly large polarization even for a nearly symmetric resonance suggesting a small interference.
