【 摘 要 】

The capture of two electrons accompanied by the simultaneous emission of a single photon (RDEC) has been investigated for 2.11 MeV/u fluorine ions (F8+and F9+) colliding with gaseous N2and Ne and upper limits on the cross sections are determined. The measurements were performed at Western Michigan University using the tandem Van de Graaff accelerator. Preliminary analysis indicates that the RDEC cross sections for F9+for both targets are very close in magnitude and comparable to previously recorded cross sections for fully-stripped ions colliding with thin-foil targets. The states of observable RDEC capture are discussed, as well as future work.
