Abstract

High resolution x-ray spectroscopy has been used to measure FK x rays resulting from the decay of doubly excited two electron states formed during F8+ + He, Ne, or Ar collisions. The energy range spanned by the spectrometer includes the 2s2p(3p) ls2s(3S), 2s2p(1P) + ls2s(lS), 2p2(1D) ls2p(lp), 2p2(3p) + ls2p(3p) and the 2p2(1S) ls2p(1P) 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.
