We have calculated differential cross sections for the process of resonant transfer excitation followed by Auger emission (RTEA) in collisions of H-like fluorine with H{sub 2}. At energies below the {ital KL}{infinity} limit, our results for the emission of {ital KLL}, {ital KLM}, and {ital KLN} Auger electrons agree qualitatively with the experimental results of Schulz {ital et} {ital al}. (Phys. Rev. Lett. 62, 1738 (1989)) for transfer excitation (TE) that have been normalized to our {ital KLL} RTEA cross section at 48 Ry. Together with our RTEA results for {ital KLO} emission, this implies that RTE is the dominant TE mechanism at these energies for all {ital n} values measured so far although uncorrelated transfer excitation may be important at high energies. The absolute cross sections of Schulz {ital et} {ital al}. are about a factor of 12 smaller than theory.
