Electron excitation and capture in F8+ plus Ne collisions

K x-ray spectra from the nearly symmetric collision system F8+ plus Ne were obtained over the bombarding energy range from 10 to 40 MeV with sufficient spectral resolution to observe separately the K x-ray transitions from states formed by K-shell electron excitation and electron capture to excited states of fluorine. The cross sections for the two processes were obtained by normalization to total K x-ray production cross sections. The K x-ray production cross section for electron capture to excited states falls off by a factor of 40 over the energy range of 10 to 40 MeV, and the K-shell electron excitation cross section increases by a factor of 4 over the energy range 20 to 40 MeV. The K-shell excitation cross section has an energy dependence quite different from that observed for the asymmetric systems
