High resolution x-ray spectroscopy has been used to measure F K x rays resulting from the decay of doubly excited two electron states formed during F/sup 8 +/ + He, Ne, or Ar collisions. The energy range spanned by the spectrometer includes the 2s2p(/sup 3/P) ..-->.. 1s2s(/sup 3/S), 2s2p(/sup 1/P) ..-->.. 1s2s(/sup 1/S), 2p/sup 2/(/sup 1/D) ..-->.. 1s2p(/sup 1/P), 2p/sup 23/P) ..-->.. 1s2p(/sup 3/P) and the 2p/sup 2/(/sup 1/S) ..-->.. 1s2p(/sup 1/P) transitions. These states may be formed by nonresonant transfer excitation, in which electron excitation is coupled with electron capture to an excited state, or by resonant transfer excitation, a process related to dielectronic recombination, in which the capture of a loosely bound target electron results in projectile electron excitation. Calculations have been performed to estimate the contribution of each process to the total measured cross section.
