Abstract
Electron capture to levels of projectiles lead to three-electron ions with an energetically allowed -Auger decay channel. We have measured the F -Auger emission spectra for collisions with thin gas targets of He and Ne with sufficiently high resolution to distinguish capture to several of the low-lying values. The -Auger production cross sections are reported as a function of the level into which the electron is captured. The -level dependence is measured for projectile energies of 6, 9, 12, and 15 MeV and is compared to the Oppenheimer-Brinkman-Kramers OBK model for charge transfer and to a function. The measured -Auger electron-production cross sections closely follow the function which differs from the predicted OBK dependence, even though the cross sections for the higher levels agree with the predicted OBK energy dependence. The effects of cascading upon the calculated dependence are also studied.
