Electron-electron interactions in transfer and excitation inF8+→H2collisions

We have measured projectile Auger electrons emitted after collisions of H-like F with ${\mathrm{H}}_2$. The cross sections for emission of KLL, KLM, KLN, and KLO Auger electrons show maxima as a function of the projectile energy. One maximum in the KLL emission cross section is due to resonant transfer and excitation. A second maximum in the cross section for KLL emission as well as the maxima in the emission cross section for the higher-n Auger electrons are attributed to a new transfer and excitation process. This involves excitation of a projectile electron by one target electron accompanied by the capture of a second target electron.
