辐射双电子捕获 (RDEC) 是离子原子碰撞中发生的一步过程，已针对裸氟离子与碳的碰撞进行了研究。当两个目标电子被捕获到射弹的束缚态并同时发射单个光子时，RDEC 就完成了。这项工作是我们早期对裸氧射弹进行 RDEC 测量的后续工作，从而在两种情况下提供了一个没有电子相关库仑场的接收系统，并允许对两个碰撞系统以及可用的理论研究进行比较。还讨论了可能有助于 RDEC 能量区域作为背景过程的 X 射线发射的最重要机制。
Radiative double electron capture (RDEC), the one-step process occurring in ion-atom collisions, has been investigated for bare fluorine ions colliding with carbon. RDEC is completed when two target electrons are captured to a bound state of a projectile simultaneously with the emission of a single photon. This work is a follow-up to our earlier measurement of RDEC for bare oxygen projectiles, thus providing a recipient system free of electron-related Coulomb fields in both cases and allowing for the comparison between the two collision systems as well as with available theoretical studies. The most significant mechanisms of x-ray emission that may contribute to the RDEC energy region as background processes are also addressed.
